The light touch switch adopts the kidney-shaped metal elastic sheet, and has the advantages of good elasticity, long service life and simple manufacturing.
Description
Technical field
The utility model relates to a kind of switch, and more particularly, it relates to a kind of touch-switch.
Background technology
A kind of touch-switch, comprise, pedestal, for spill box-like, the box-like cavity that has rectangle of spill, there are pre-buried inner side fixed contact and outside fixed contact in the bottom surface of cavity, the top end face of outside fixed contact is placed the metal clips that arches upward at middle part, this metal clips is rectangle, rectangle metal clips in have two parallel groovings, article two, parallel grooving is divided into three elastic strips by rectangular metal shell fragment, the elastic strip of both sides is positioned at the top of outside fixed contact, the elastic strip of both sides has stamping forming impression, cause making the elastic strip physical length of both sides to shorten, thereby the elastic strip that makes middle part arches upward the elastic strip at middle part be positioned at inner side fixing get an electric shock directly over, button is conflicted through the elastic strip at cover plate central part through hole and middle part, the shortcoming of this touch-switch is that the grooving of metal clips can cause the elasticity of metal clips to reduce, because the width of elastic strip is narrower, fatigue resistance reduces, cause reduce useful life, the structure of rectangle is comparatively complicated simultaneously, manufacturing cost is high.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of touch-switch, adopts the metal clips of kidney-shaped, good springiness, the life-span is long, manufactures simple.
For achieving the above object, the utility model provides following technical scheme: a kind of touch-switch, comprise pedestal, cover plate, described pedestal is that spill is box-like, pedestal comprises the cavity of rectangle, there are pre-buried inner side fixed contact and outside fixed contact in the bottom surface of cavity, on described pedestal, be also provided with and inner side fixed contact, the pin of outside fixed contact conducting, the top end face of outside fixed contact is placed metal clips, there is arching upward of inner side fixed contact direction dorsad at described metal clips middle part, on cover plate, be equipped with the button of conflicting with metal clips middle part, described metal clips is kidney-shaped.
By adopting technique scheme, metal clips is kidney-shaped, make metal clips in punch process work, can directly there is elasticity, without grooving in metal clips, what keep metal clips is a complete integral body, elasticity is better, in use procedure, button is pressed after relieving, can upspring rapidly, avoid the generation of electric arc, protection contact and metal clips, simultaneously because metal clips is complete integral body, therefore can there is stronger endurance life, improve the life-span in useful life, because the metal clips of kidney-shaped is without grooving, with punching press impression, reduced manufacturing procedure, manufacture simple, reduced manufacturing cost.
The utility model is further set to: two sections of circular arcs in the metal clips of described kidney-shaped are positioned at same circumference on week.
By adopting technique scheme, the metal clips of kidney-shaped forms after can directly cutting both sides circular arc by typical circular metal clips, and the manufacture of typical circular metal clips is simple, and process is ripe, can obtain the metal clips of the good kidney-shaped of quality.
The utility model is further set to: four angles of the rectangle cavity on described pedestal are equipped with chamfering.
By adopting technique scheme, four chamferings of the rectangle cavity on pedestal can make the metal clips of kidney-shaped and rectangle cavity more chimeric, prevent from entering impurity between contact and shell fragment.
The utility model is further set to: described inner side fixed contact and the equal annular spread of outside fixed contact, the radius of a circle at fixed contact place, described inner side is less than the radius of a circle at fixed contact place, outside.
By adopting technique scheme, the metal clips of kidney-shaped forms after cutting circular arc by circular metal shell fragment, therefore when button makes metal clips distortion, inner side fixed contact can be positioned on the same circumference of metal clips, outside fixed contact can also can be positioned on the same circumference of metal clips, increase contact area, thereby increase conducting effect.

Embodiment
Referring to figs. 1 through Fig. 7, the utility model touch-switch embodiment is described further.
A kind of touch-switch, comprise pedestal 1, cover plate 2, described pedestal 1 is that spill is box-like, pedestal 1 comprises the cavity 11 of rectangle, on four angles of rectangle cavity 11, be equipped with chamfering, there are the inner side fixed contact 6 of the annular spread of being embedded with and the outside fixed contact 7 of annular spread in the bottom surface of cavity 11, on described pedestal 1, be also provided with and inner side fixed contact 6, the pin 5 of outside fixed contact 7 conductings, the top end face of outside fixed contact 7 is placed with the metal clips 4 of kidney-shaped, two sections of circular arcs of the metal clips 4 of kidney-shaped are positioned on same circumference, there is arching upward of inner side fixed contact 6 directions dorsad at metal clips 4 middle parts, on cover plate 2, be equipped with the button 3 of conflicting with metal clips 4 middle parts.
By adopting technique scheme, metal clips 4 is kidney-shaped, make metal clips 4 in punch process work, can directly there is elasticity, without grooving in metal clips 4, what keep metal clips 4 is a complete integral body, elasticity is better, in use procedure, button 3 is pressed after relieving, can upspring rapidly, avoid the generation of electric arc, protection contact and metal clips 4, simultaneously because metal clips 4 is complete integral body, therefore can there is stronger endurance life, improve the life-span in useful life, because the metal clips 4 of kidney-shaped is without grooving, with stamp out impression, reduced manufacturing procedure, manufacture simple, reduced manufacturing cost, two sections of circular arcs in the metal clips 4 of kidney-shaped are positioned at same circumference on week, the metal clips 4 of kidney-shaped forms after can directly cutting both sides circular arc by typical circular metal clips, and the manufacture of typical circular metal clips is simple, and process is ripe, can obtain the metal clips 4 of the good kidney-shaped of quality, four angles of the rectangle cavity 11 on described pedestal 1 are equipped with chamfering, and four chamferings of the rectangle cavity 11 on pedestal 1 can make the metal clips 4 of kidney-shaped more chimeric with rectangle cavity 11, prevent from entering impurity between contact and shell fragment, the metal clips 4 of kidney-shaped forms after cutting circular arc by circular metal shell fragment, therefore when button 3 makes metal clips 4 distortion, inner side fixed contact 6 can be positioned on the same circumference of metal clips 4, outside fixed contact 7 can also can be positioned on the same circumference of metal clips 4, increase contact area, thereby increase conducting effect.
