Abstract
The utility model relates to a pull switch for illumination, overcoming the defect that a common pull switch can not discern switching state visually. The end head of a cam in the pull switch is provided with a chamfered tooth plate rotating synchronously, and a display plate is supported by the chamfered tooth plate to move up and down. The display plate is movably arranged in the guide groove of the side edge of a support frame, the support frame is arranged on a switch base, an offsetting spring is arranged between the upper end of the display plate and the support frame, and the display plate is pointed to the hole of a switch shell. The utility model having simple structure, easy fabrication, low cost and reliable display can be used as a switch for illumination.
Description
The utility model relates to a kind of electric switch, particularly a kind of pulling switch with display.
At present the defective that exists with the employed lighting electric switch of premises in public places is exactly to have a power failure or the illuminating lamp of its control when having broken, be difficult to judge its on off state, after the power failure that switch backguy pulling is several down, it still is disconnected not knowing logical, if switch is in the position of " leading to ", in case behind the incoming call, and when nobody, electric energy has just been wasted in vain, has also caused unnecessary economic loss to the user, makes troubles for people's life.
The purpose of this utility model is to provide a kind of simple in structure, pulling switch that can reliable display switch state.
The utility model is realized with following mode: a kind of pulling switch with display, it comprises pulling switch 5, angle gear piece 4 fixedly is equipped with in the termination of the cam 6 in pulling switch 5, above angle gear piece 4, head on display piece 1, display piece 1 activity is contained in the groove on the support 3, between the upper end of display piece 1 and support 3 back-moving spring 2 is housed, and support 3 is contained on the base 7 of pulling switch 5, have hole 11 on the cap 9 of pulling switch 5, the hole 11 on the cap 9 is pointed in the upper end of display piece 1.There is sweep the lower end of display piece 1, and the width of its sweep is greater than the thickness of angle gear piece 4, at the coloured demonstration cover 8 of the upper end of display piece 1 suit.Angle gear piece 4 adopts triangular piece.
The utlity model has simple in structure, be easy to make, easy to use, cost is low, adopts the protruding commentaries on classics in the switch to drive angle gear piece rotation, shows and head on upper and lower the moving of display piece, have and show reliably, will never cause mistake to show that for saves energy provides convenience, it is applicable to as bull switch.
Fig. 1 is the utility model structural representation.
Fig. 2 is the end view of the utility model cam and angle gear piece 4
Fig. 3 is the display piece scheme of installation
Fig. 4 is the schematic perspective view of coloured demonstration cover 8
Fig. 5 is the utility model stereoscopic schematic diagram
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the pulling switch of the utility model band display is that the outside by the rotation conducting strip 10 of the termination of the bakelite cam 6 in the common pulling switch 5 is by being equipped with angle gear piece 4, angle gear piece 4 is installed on the cam 6, rotate with cam, cam 6 is contained on the axle 12, angle gear piece 4 adopts three angle teeth, as shown in Figure 2.Head on display piece 1 above angle gear piece 4, as shown in Figure 1, display piece 1 activity is contained in the guide groove on support 3 sides, between the upper end of display piece 4 and support 3 back-moving spring 2 is housed, and as shown in Figure 3, support 3 is contained on the pulling switch base 7, as shown in Figure 1.When backguy hauls cam 6 rotations, cam 6 band angle of entry gear pieces 4 rotate, and angle gear piece 4 heads on display piece 1 upper and lower moving, the end portion bending of angle gear piece 1, the width of its sweep is greater than the thickness of angle gear piece 4, adopt triangle gear piece 4, make cam 6 when rotating 60 °, switch conduction, the top of the horn of this hour angle gear piece 4 heads on display piece, make display piece 1 stretch out hole 11 on the switch cap 9, represent that switch is at conduction position, as shown in Figure 5 this moment.And behind rotating cam once more, display piece is under the effect of back-moving spring 2, get back to the minimum point between two jiaos of angle gear piece 4, also be that display piece 1 is withdrawn in the cap 9 of pulling switch, the position that the expression switch disconnects, the cover adularescent shows cover 8 in the upper end of display piece 1, is beneficial to distinguish with this cap of black glue.The pulling switch of this band display is applicable to single line and two-wire switch.
