Description

The button of tool diode displaying state

The utility model provides a kind of button, refer to especially a kind of button itself promptly have light-emitting diode the button of tool diode displaying state.

The control button of electric equipment products as shown in Figure 5, includes a Switch main body 50, and the top is established one and pressed key 51 in the central, the outer cover 52 that this top of pressing key 51 then can sheathed one suitable shape, and this outer cover 52 is exactly " button " that electrical equipment is controlled for the user in appearance; Use such structure, because button is when being touched by pressure, be once " opening ", the circulation pattern of " pass " once, but be not easy in appearance to find out that this push-button switch is in " opening " or "off" state actually, therefore the misoperation of false touch button happens occasionally, and is the major defect of commonly using button; Again or on casing for electric appliances, set up a hole, can add a light-emitting diode on it, when button is "open" state, this light-emitting diode is switched on and is luminous, but such structure forms for organizing to establish in addition, and is inconvenient in processing, establishes assembly hole in addition on the casing for electric appliances again in addition, manufacturing cost is increased, and all is the shortcoming of commonly using button.

Main purpose of the present utility model is to provide a kind of button of tool diode displaying state, pushing is during outer cover, and push-plate is with pressing key to sink, and light-emitting diode is subjected to the conducting of circuit and luminous, light appears from outer cover, more convenient and saving cost in assembling processing.

The technical scheme that the utility model adopted is: a kind of button of tool diode displaying state, the Switch main body that comprises several utmost point pin of a tool, its top is provided with the pressure key, a sheathed outer cover above the pressure key, push outer cover, circuit is out, a circulation pattern that closes; It is characterized in that: the push-plate of a tool mesopore, respectively be provided with a baffle plate in both sides, push-plate is placed in mesopore on the end difference of pressing key and fixes; At least one LED light-emitting diode is located between two baffle plates of push-plate top, and its utmost point pin descends along body and circuit board joins; Outer cover is at least translucent; The pushing outer cover, push-plate is with pressing key to sink, and light-emitting diode still stays put, and the conducting that is subjected to circuit is and luminous, and light can appear from outer cover.

Described pressure key both sides are provided with catching groove; Inwardly respectively be provided with a snap-on below baffle plate, when push-plate was placed in the end difference of pressing key with mesopore, snap-on was fastened in this catching groove, and the location really; The two ends of described push-plate respectively are provided with the detent of a proper width, and the two poles of the earth pin difference of light-emitting diode groove is thus transferred and descended.

The beneficial effects of the utility model are: 1. the utility model comprises the Switch main body of several utmost point pin of a tool, and its top is provided with the pressure key, and a sheathed outer cover above the pressure key is pushed outer cover, and circuit is out, a circulation pattern that closes; The push-plate of one tool mesopore respectively is provided with a baffle plate in both sides, push-plate is placed in mesopore on the end difference of pressing key and fixes; At least one LED light-emitting diode is located between two baffle plates of push-plate top, and its utmost point pin descends along body and circuit board joins; Outer cover is at least translucent; The pushing outer cover, push-plate is with pressing key to sink, light-emitting diode still stays put, and the conducting that is subjected to circuit is and luminous, and light can appear from outer cover, and the light that button of the present utility model itself promptly has a light-emitting diode shows "on" position, winding in addition, also needn't on casing for electric appliances, establish relative ccontaining hole slot, more convenient and saving cost in assembling processing, this is a major advantage of the present utility model.

2. the utility model is established two baffle plates on push-plate, and light-emitting diode is located in the middle of it, can prevent also that at ordinary times it is subjected to stir improperly; effect with protection, in addition, easy and outer cover assembly; more intimate and convenient in the use, be another advantage of the present utility model.

3. because groove is established at push-plate of the present utility model two ends, make the utmost point pin of light-emitting diode following therefrom, have the effect of location; Press the key both sides to establish catching groove, inwardly respectively be provided with a snap-on below baffle plate, when push-plate was placed in the end difference of pressing key with mesopore, snap-on was fastened in this catching groove, made the push-plate location really, and therefore, the utility model structure is firm, is another advantage of the present utility model.

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
