FIGURE 7 is a partially sectioned elevational View of the assembly of FIGURE 6.

FIGURE 8 is an end view of a component of structure in FIGURES 6 and 7.

FIGURE 9 is a fragmentary sectional view taken along line 9-9 in FIGURE 2.

FIGURE 1 shows a fragmentary plan view of a motor vehicle dashboard 10 having a storage compartment 11 box-like shape and open along one side subject to closure by a cover or member 12 hinged in a suitable manner relative to the dashboard 10. The pivotal or hinged relationship of member 12 to the dashboard 10 is indicated further in FIGURE 2. The box-like compartment 11 can be formed of any suitable material used to provide walls having a periphery thereof secured to one side of the dashboard. Means for illuminating such a compartment 11 are generally energized and tie-energized in accordance with opening and closing of access to the compartment 11 by latching and unlatching of the cover member 12 relative to the dashboard. Adjacent to a corner of the compartment 11, there is a metal mounting flange 13 integral with the dashboard 10 or carried thereby and having an opening or aperture 13a of a predetermined diameter to permit mounting and insertion of a combined lamp-retainer and switch means generally indicated by numeral '14 having features in accordance with the present invention.

Components and structure in a lamp-retainer and switch assembly can include the following parts. First, there is a centrally apertured plug-like mounting button 14b having a plurality of cam-like spring fingers 14f adapted to provide resilient peripheral engagement relative to an inner edge of the mounting aperture 13a. The plug-like button 14b is mounted concentrically outside a cylindrical metal sleeve or eyelet 15 visible in FIGURES 2-3 and 6-7. This metal sleeve or eyelet includes a pair of radially outwardly bent or swaged flanges 15 such that a guide means 16' can be fitted thereto as a cantilever mounting in accordance with the present invention. FIGURES 2-3 and .6-7 as well as 9 illustrate the guide means 16 including a pair of substantially parallel rail portions 16r joined to each other by a transverse end portion 16e tofor-m a closed loop of wirelike material extending laterally from the sleeve 15 and spring-finger button chiefly on a back side of the aper-' tured mounting panel 13. Substantially in planar alignment with the apertured panel 13, there are opposite ends wrapped or twisted as indicated by numeral 161 aroundl and the remaining end terminates as a radially outwardly extending abutment 16a engageable by an end 17a of a tension spring means 17. Axial or longitudinal lengths of the metal sleeve or eyelet is such that substantially two turns of the rail means ends can be made between flanges 15f so as to effect wedging of these ends against one side of the plug-like button 14b as illustrated in the drawings.

Spring means 17 has another C-shaped end 170 hooked into engagement with a projection or semi-circular eyelet 1-8 of insulating material integral and carried by an insulating body 20. The insulating body includes a socket or lamp-retainer portion 21 having a hollow interior 21h and an open end 21e into which a base such as 22w of a lamp bulb 22 can be fitted. Length of the substantially parallel side rails 16;" is such that this bulb 22 can be moved reciprocally in an axial direction therebetween for a predetermined distance corresponding to a path of movement of the socket or lamp retainer portion 21 in response to opening and closing of the cover or member 12 on one side of the compartment .11. The insulating body includes an intermediate portion 2th 'that joins the socket or lamp retainer portion 21 integrally with an axially extending plunger 24a having a curved end 242 engageable by one side of the cover or member 12.

FIGURE 4 is an end view of the insulating body 20 alone including the integral socket or lamp retainer portion 21 as well as the plunger or axial projection 24a joined to each other by the intermediate portion 201'. An axial recess 201' is defined by the intermediate portion 20i and communicates at one end with the hollow interior 21h of the socket or lamp-retainer portion 21. The recess Mr is open also along a bottom side but is closed laterally by downwardly extending flanges 20 A pair of lateral web-like extensions 20w are provided extending integrally from the insulating body 20 to a width externally substantially the distance between the substantially parallel rail portions 161* as visible in FIGURES 3 and 4. Each of these web-like portions 20w forms a bottom of a recess or U-shaped groove further defined by an upper pair of integral projections 20a and a lower pair of integral projections 20L provided in longitudinally spaced apart relationship to each other on each of separate sides of the insulating body 20. FIGURES 3 and 4 show the upper projections 20w extending laterally outwardly from the socket or lamp-retainer portion 21 and lower projections 20L spaced laterally apart and longitudinally away from the upper projections such that a pair of upper and lower projections on each side straddle the rail portion 16r and are substantially complementary thereto and slidably engageable along each of the substantially parallel rail portions. These upper and lower projections as well as the plunger 24a extending through the central aperture of the plug-like button 14b and hollow sleeve 15 serve to stabilize reciprocal movement of the insulating body 20 relative to the cantilever-like support of the guide means 16 carried by the sleeve and plug-like button.

Metal electrical connector means can be fitted to the hollow interior 21h of the socket or lamp-retainer portion of the insulating portion 20. Electrical connector means illustrated in the drawings are for use with an electric light bulb 22 having a glass web base portion 22w of a type shown and described both in U.S. Patents 2,924,736-Kotsch and 2,937,308-Howles et al. The electrical connector means include a pair of U-shaped contacts 24a and 26 respectively similar to contacts disclosed in a copending application, S.N. 628, filed January 5, 1960, and belonging to the assignee of the present invention. FIGURE 3 of the drawings indicates such a U-shaped contact in an end view integral with terminal means 24 adapted for use in accordance with the present invention. Terminal means 24 as seen in FIGURES 2 and 3 includes not only the U-shaped contact portion 24, but also a longitudinally extending male blade portion 24m laterally offset by an intermediate portion 241' integral with an embossed portion 24e for strength between the male blade 24m and the intermediate portion 241' as well as barbed binding portion 24b. This barbed binding portion 24b has pairs of oppositely extending projections that frictionally engage opposite inner surfaces of the hollow interior 21h so as to maintain the U-shaped portion 24a and male blade portion 24m in a predetermined positioning relative to the socket or lamp-retainer portion 21. As indicated schematically in FIGURE 2, the male blade portion 24m is adapted to be electrically engaged by a female terminal means F electrically energized from a battery 13 suitably grounded in a well-known manner. The female terminal means F can be of a type disclosed in US. Patent 2,682,038 Johnson, belonging to the assignee of the present invention. This female terminal means F is connected to the male blade portion 24m after the lamp-retainer and switch means 14 is mounted in the apertured panel or flange portion such as 13. The U-shaped contacts 24a and 26a establish electrical connection with filament means (not shown) of the lamp bulb 22. The U-shaped contact portion 26a is integral with an extension 26e projecting resiliently through the recess 20r and terminating in a bifurcated end portion or transverse slotted flange 26 adapted to abut against a transverse or vertical wall portion 20v joining the intermediate portion 2th as well as the substantially parallel flange portions 20f. It is apparent that the bifurcated end or flange portion 26 visible in FIGURE 5 is adapted to fit complementary to and straddle the plunger portion 24a used as an actuator to effect reciprocable shifting of the insulating body 20 in response to movement of member 12 and along a linear path defined by the rail portions 16r of the guide means 16 in accordance with the present invention. The U-shaped contact portion 26a as well as the extension 26e and bifurcated or flanged end 262 form a secondary terminal means 26 further including barbed binding portions 26b both visible in FIGURE 5. When the cover or member 12 is pivoted to a position permitting access to the compartment 11, the plunger or actuator portion 24a is shifted to the right as seen in FIGURE 2 due to normal biasing by tension spring means 17 stretched between the abutment 16a and eyelet 18 as described earlier. Thus the terminal contact means as well as the insulating body 20 and integral actuator or plunger 24 together with the lamp bulb 22 mounted relative to the contacts move as a unit guided by rail portions 161'. In FIGURE 2, there is phantom outline of the bifurcated or flange end 26 of contact 26 together with a phantom positioning of the end 24e of the plunger or actuator 24a engaged by the cover or movable member 12 so as to interrupt electrical connection between the bifurcated end or flange portion 26 and a flange 15] of the sleeve or eyelet 15 attached to the metal plug-like button 14b snapped into engagement with the metal mounting panel 13 suitably grounded electrically as schematically indicated in FIGURE 2. The bifurcated or flange end portion 26; of the terminal means 26 effects stabilization of the engagement of this terminal means to the insulating body 20 and assures positive electrical engagement of the sleeve or eyelet 15. The rail portions 16r provide resilient cantilever support for the insulating body 20 which carries the electrical means as well as the lamp bulb 22. The female terminal means F and any suitable electrical housing or covering therefor also move together with the male blade portion 24m in a to and fro path. The female terminal means can be suitably attached to an end of an insulating conductor which extends from a suitable wiring harness behind the dashboard cap. The combination lamp socket body and plunger shown in FIGURE 2 and elsewhere in the drawings can slide on wire guides with the plunger or actuator sliding through the sleeve or eyelet which holds the wire guide and plug-like button together for cantilever-like mounting. Projections 20a and 20L serve as means forming guide bearing surfaces integral with the insulating body such as 20. The struc ture and assembly of FIGURES 2 and 3 is such that lateral dimensions thereof permit insertion of the combination lamp-retainer and switch means through a mounting aperture such as 13a even when the bulb 22 is fitted to the terminal means 24 and 26 prior to mounting of the assembly in the dashboard.

It is to be understood that in some instances, it may be desirable to have the lamp bulb extend laterally transversely relative to the linear path of movement established by the guide means such as 16. A slightly shorter length of guide means can be used when the lamp bulb is insertable transversely rather than axially as shown in FIGURES 2 and 3. Also, replacement of such lamp bulb means can be facilitated by having the lamp bulb mounted transversely or substantially at right angles with respect to the path of movement established by the rail portions 16r of the guide means 16. Accordingly, in FIGURES 6 and 7, there is shown an insulating body 34) having a socket or lamp-retainer portion 31 with a. hollow interior 31h comparable to the socket 21 but located to have an open end 312 provide access to the hollow interior substantially at right angles to the path reciprocal movement established by guide means such as 16. Except for this modification of the socket portion of the insulating body, parts such as the guide means, plug-like button, tension spring means 17 and sleeve or eyelet 15, are identical in structure and purpose described previously with reference to other views and therefore identical reference numerals are applied where such similarity exists. Insulating body 30 has a hook portion 2%; carried thereby and engaged by an end 17c of the spring 17. The insulating body 30 includes a slot 31s which extends from the hollow interior 3111 to the outside thereof such that a terminal means 34 having a male blade end portion 34m can project axially from the insulating body and can be engaged by a female terminal means such as F indicated in FIGURE 2. The terminal means 34 also includes a U-shaped contact portion 341: integral therewith and joined to the male blade portion 34m by an elbow portion 342 that fits into the slot 31s. The blade portion 34m is initially longitudinally in alignment with the elbow portion 342 but after insertion of the blade portion and the elbow portion through the slot 34s, the blade portion 34m is bent substantially at right angles to the elbow portion so as to extend axially from the insulating body 30 and substantially parallel to the side rail portion 161' of the guide means 16. Thus, the male blade portion again provides means for connecting a source of power for energization of the light bulb connectible to terminal means in the socket 31. In addition to terminal means 34 with the integral male blade portion 34m, there is a secondary terminal means 36 including a U-shaped contact portion 361! also fitted into the hollow interior 31h of the socket 31. Terminal means 36 includes a lateral flange mounting portion 36 which can have barbs for binding purposes with a configuration similar to that identified by reference numeral 26b in FIGURE 5. The terminal means 36 also includes an extension 362 that terminates in a crescent-shaped end or bifurcated flange contact portion 36F electrically engageable with the sleeve or eyelet such as 15. This bifurcated end is adapted to straddle plunger or actuator portion 34a with an end 342 and integral with an intermediate body portion 30i of the insulating body 30. The bifurcated end 36F is backed by a vertical wall portion 30v and bearing surfaces for engagement between the guide means and insulating body 30 and include upper lateral projections 3011 as well as lower lateral projections 30L visible in FIGURES 6, 7 and 8. The assembly of FIGURES 6 and 7 including the insulating body 30 can be fitted through a mounting aperture such as 13a without the lamp bulb inserted into position. The lamp bulb such as 22 can be fitted to the terminal means 34 and 36, particularly the U-shaped contact portions 34a and 3611 respectively. The integral plunger 34a and socket 31 of the insulating body 30 can be inserted between the wire guides or rail portions 161' sideways during subassembly thereof such that the insulating body 30 can be turned about its longitudinal axis until temporary spreading of the resilient wire portions or rails 16r results in co-planar or parallel alignment of the guide surfaces of the insulating body relative to the rail portions 161'. After this assembly, the transverse end 162 of the Wire guide means in a location opposite to the end secured to the plug-like button and sleeve or eyelet can be bent substantially at right angles as indicated by reference numeral 16E into limit stop indicated in FIGURES 6 and 7. This limit stop 16B is engageable by the lower lateral projections 30L for example and the transverse end portion 162 provides a guard or shield for any light bulb such as 22 fitted into the U-shaped contact portions 34;: and 36a to project substantially transversely to the path of to and fro move ment. Energization and de-energization of the lamp bulb is effected by engagement of the end Me of the plunger or actuator 34a integral and shiftable together with the contact means as well as the socket portion 31 of the insulating body 30.
