Description

Improved pullswitch with on/off display

The utility model relates to a kind of switch of electricity of energy display switch operating state, particularly a kind of pulling switch that can show " leading to ", " breaking " operating state.

Chinese patent application provide for No. 85200535 a kind of simple structure easy to use and have well lengthen the life, the stay-supported switch of energy-saving effect.But be difficult to when having a power failure judge whether it is in opens or off state.In addition, Chinese patent application provides a kind of break-make Pull-cord switch with display No. 85200377, the display area deficiency because the main element of its indicator cock break-make is too tiny, be difficult for discovering opening or off state of switch, and, since the annex occupy-place of its increase excessive so that can not lengthen the life bulb, part that energy-conservation part and switching show puts into pulling switch together.

The purpose of this utility model be to provide a kind of simple structure, easy to use, more clearly display switch " lead to ", the stay-supported switch of " breaking " operating state.

Invention is achieved in that makes cam with the column part of stay-supported switch armature, this cam can be made into disc cam or has the cam of three convex-concaves, the loam cake central authorities of pulling switch are made a dimple, open an aperture at the dimple center, in dimple, adorn an indicating arm loam cake, rely on the connecting rod that is connected indicating arm loam cake center the active force of spring to be pressed on the disc cam or be pressed on the cam with three convex-concaves; When the conversion of the once positive and negative stroke of the per 90 ° of works of disc cam (column part of pulling switch armature), promoted the indicating arm loam cake and exposed or indentation at the loam cake of pulling switch, thus novel, reach the purpose of clear indicator cock operating state simply.

The utility model is because the indicating arm loam cake can be sufficiently large, so indication is clear especially.It is simple in structure, and is easy to operate, and stopcock is energy-conservation when being convenient to have a power failure.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the loam cake of pulling switch in a kind of concrete structure of the utility model and the cutaway view of disc cam (column part of armature).

Fig. 2 is the upper cover top view of pulling switch in a kind of concrete structure of the utility model.

Fig. 3 has indicated the another kind of concrete structure of the utility model, and wherein the column part of the armature of pulling switch makes the cam of three convex-concaves.

Fig. 4 is a kind of structural representation of the utility model.

Below in conjunction with accompanying drawing the utility model is described in detail.

The utility model is made up of dimple (2), connecting rod (3), back-moving spring (4), annulus (5), cam (6), mandrel (7), backguy pivoted arm (8), runner (9), base (10), backguy (11), back pole piece (12) and the preceding pole piece (13) etc. of indicating arm loam cake (1), switch loam cake.See figures.1.and.2, the utility model makes disc cam (6) as shown in Figure 1 with the column part of pulling switch armature, the once positive and negative stroke conversion of per 90 ° of dos, the terminal point of positive stroke is corresponding to " leading to " state of switch, and the terminal point of revesal is corresponding to " breaking " state of switch.Indicating arm loam cake (1) exposed switch case when switch was put " leading to ", the end face equal with the switch outer surface (or slightly recessed) of indicating arm loam cake during " breaking " position; Perhaps, the terminal point of positive stroke is corresponding to " breaking " state of switch, the terminal point of revesal is corresponding to " leading to " state of switch, and the indicating arm loam cake exposed switch case when switch was put " breaking ", the end face equal with the switch appearance (or slightly recessed) of indicating arm loam cake during " leading to " position.

With reference to Fig. 1, Fig. 2, indicating arm loam cake (1) is the main element of indication switch on and off.The indicating arm loam cake preferably relies on the active force of back-moving spring (4) to be pressed on the disc cam (6) by the connecting rod (3) that is connected indicating arm loam cake center.The first half of connecting rod is preferably made the ball face, and it is contacted with disc cam, and to increase the life-span, contact is reliable.Both can be shaped on annulus (or cross bar) (5) at the middle part of connecting rod, the cover upper reset spring is threaded with the splicing of indicating arm loam cake or to match again; Also connecting rod and indicating arm loam cake can be injection molded into one, back-moving spring be sealed (splicing of connecting rod and annulus or with the threaded connection that matches) with annulus behind the cover upper spring.The central authorities of switch loam cake housing are made dimple (2), the dimple center has aperture can insert connecting rod, the indicating arm loam cake is in the position that embeds dimple among Fig. 1, the indicating arm loam cake prevents the rotation of indicating arm loam cake by regular hexagon cylinder or other polygon cylinders of making shown in Figure 2, also can make cylinder.The side of indicating arm loam cake and switch case aberration are bigger.

Claims (3)

1, a kind of break-make Pull-cord switch with display of being made up of base, backguy pivoted arm, loam cake, preceding pole piece, back pole piece, mandrel, runner, backguy is characterized in that:

The column part of the armature of a, described pulling switch is cam [6];

B, indicating arm loam cake [1] have back-moving spring [4] and annulus [5] in the central authorities of the dimple [2] of switch loam cake on the connecting rod [3];

The side of c, indicating arm loam cake and switch case aberration are bigger.

2, break-make Pull-cord switch with display according to claim 1 is characterized in that the connecting rod (3) and the acting surface of cam (6) are the ball faces.

3, break-make Pull-cord switch with display according to claim 1 and 2 is characterized in that indicating arm loam cake (1) makes the regular hexagon cylinder.
