Application filed November 17, 1324.
T his invention relates to a plural way electric circuit controlling lamp socket switch primarily ior the control ot low voltage eircuits as t'or automobile lighting service, in
1 the control of a plural ordouble filament head light bulb in conjunction with a tail light bulb wherein the tail light circuit is always complete or closed while the circuit is complete or closed to either of the lila- 50 ments ot the head light.
The object ot my invention is to provide a switch for selective circuit control said switch being ot' compact structure and having mounted therein a removable multiple ifi contact plate.
A more specific object is to provide a lamp socltet and switch adapted for mounting an incandescent bulb, and for separately controlling each ot' two circuits of an incandescent light of the two-filament type, as well as lfor simultaneously controlling the circuit ot a separately mounted third light or a lfilurality of such lights, to cause the circuit to the latter to be closed or opened 35i when either of the circuits to the other two is closed or opened, whereby the third light or circuit is operated in proper correspondence to the others.
The invention herein is applied for conf trolling circuits to the two-.lilament light or bulb such as is used on automobile headlights, in which the dimmer and bright light are combined iu a single bulb, and the separate circuits for each lilament provided, the
:f1 terminals o'l which lilanients are connected through au improved switch in such manner as to control a tail light circuit, whereby that circuit is active or inactive in correspondence to either of the first mentioned i circuits.
Another object is to provide a switch or contact disk oi insulating material as an intermediate connector element adapted for electrically connecting the terminals oit the a two-lilament incandescent lamp to a pair of adjustable switch elements in such manner that the filament can be separately energized, and an auxiliary circuit correspondingly energized simultaneously therewith.
Another object is to provide means for removably securing the bulb at one side of and in contact with the switch or contact disk and to further provide means for mounting a contact carrying plug of insulating material as a finger piece at the opposite side fil) Serial No, 750,228.
