Abstract

The utility model relates to a button switch which is composed of an interlocking mechanism, a button fixed on a panel, and a bonding box provided with a spring, a bonding post and a contacting piece. A straight shaft provided with the spring and the contacting piece is arranged into a shell body fixed with the bonding post and a silver contacting point. The shell body is pressed and matched with a shell cover. The shell and the straight shaft are connected into a whole through a positioning steel wire, so as to form the interlocking mechanism. Besides good contacting and insulation property and long service life, the utility model also has the advantages of double control function and light hand feeling. The position for opening or closing is obvious and is easy to identify. The panel and the wire connecting box adopt a connecting structure that screws on the back surface of the panel are fastened with an inclined sliding slot on the bonding box, so that the surface of the panel has no screw holes, which is beautiful and shapely, and the loading and unloading are convenient and require no tools.

Description

Push-button switch

The utility model relates to a kind of electric switch, key switch.

Existing commercially available switch on wall mostly is the moving seesaw-type structure, poor, the easily arcing of its contact performance, and useful life is short.The patent No. 91229376.4 " the luminous type push switch " though improved the shortcoming of wane type switch, the operating state of Push And Release is difficult to difference, and feel can not realize two controls than escheat.

The purpose of this utility model is to provide a kind of key switch, and the push-button switch contact performance is good, good insulation preformance except that possessing, and outside the advantage of long service life, also has two control functions, and the position that opens or closes is obvious, and feel is light and handy, and panel is elegant in appearance, and is easy to loading and unloading.

The utility model is achieved in that by the button that is fixed on the panel, be placed with spring, binding post, the terminal box of contact and interlinked mechanism are formed, be fixed with binding post and silver contact and be press-fitted in the housing of cap and put into, by positioning wire housing and d-axis are linked to be one and wholely constitute interlinked mechanism by the d-axis that has spring and contact.

Fig. 2. d-axis structural representation (enlarged drawing).

Fig. 3. the right view of Fig. 2 (enlarged drawing).

Fig. 4. open or close position view.

Fig. 5. panel and terminal box syndeton schematic diagram.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Panel (1) is square, has one or more button hole, both sides, the back side to have two centres that the fixed leg of screw is arranged in the middle of the surface.Terminal box (17) is square with panel (1) coupling, and gradient on the corresponding position of fixed leg on inner chamber both sides and panel (1) back side is 10～20 ° chute (16).

Have in the middle of the d-axis (3) upper and lowerly for double V-shaped and the circle round break-make piece (14) of groove of level Four ladder is arranged, sidewall vertically embeds

The silver-plated contact of shape (11) is placed contact spring (10) in two holes, lower end.Three binding posts (13) are press-fitted with housing (2) with three silver contacts (12) and are injection molded into one.

D-axis (3) upper end that will install spring (10), contact (11) is inserted in spring (7) again, is embedded partition (5), put into housing (2), positioning wire (8) two ends are inserted respectively in the break-make piece (14) of housing (2) hole and d-axis (3), again cap (9) and housing (2) are press-fitted, be inserted in spring (6) again, load onto button (4), then a switch core is assembled into, and as required one or more switch core is press fit in the switch hole at panel (1) back side.And the screw (15) on the panel (1) passed chute (16) on the terminal box (17), along tiltedly chute (16) tension downwards, be about to panel (1) and be connected in aggregates then with terminal box (17).

During use, press button (4) downwards with hand and drive d-axis (3) motion one segment distance, resilience one segment distance again, at this moment positioning wire (8) has been finished two stage steps and has been moved in the step trough of break-make piece (14), just withstands in the V-type top slot of lower end shown in Fig. 4 a, after contact this moment (11) breaks away from the C contact, with the A contacting, be that contact B, A connect the position that is in out, when external force is removed, the position that d-axis (3) also has been bound to out button (4).

If in the time of will closing, after pressing button (4) again and making d-axis (3) move downward a segment distance once more, resilience one segment distance again, at this moment positioning wire (8) has been finished second two stage steps and has been moved in the step trough of break-make piece (14), just get back to original position, withstand in the groove at V-type top, upper end shown in Fig. 4 b, contact this moment (11) breaks away from behind the A contact and C contacting, B, C contact this moment.If at this moment the C contact not wiring promptly be single control, be the position of closing, button (4) maintains an equal level with panel (1).If want two controls to make the A contacting (even another switch is in out state) of C contact and another switch, the single, double control of switch can freely be selected.

The utility model compared with prior art, remove because automatically removing the generation that oxide layer is avoided spark owing to friction energy between contact and the contact, contact performance well outside, also because of the screw on panel and the terminal box employing panel back side and the syndeton of the oblique chute fastening on the terminal box, make panel surface not have screw, panel is elegant in appearance, easy to loading and unloadingly need not use instrument, the position that opens or closes is obviously easy to identify, and can be used for the double control switch use.
