Problems solved by technology

[0003] However, each of the buttons 200 is in one-to-one correspondence with each of the contact switches 100, and pressing a certain button 200 can only achieve the operation of one corresponding contact switch 100, so the linkage of multiple contact switches 100 cannot be realized.

Abstract

The invention provides a linked contact switch structure, which comprises three contact switches, two side buttons, a linked button and a central button, wherein the three contact switches are arranged on the circuit board and arranged in the same line; each side button has a side pressing body inserted into a shell and a side spring arranged between the side pressing body and the surface of the shell, and a linked edge is arranged at a position close to the bottom part of the side pressing body; the linked button comprises a linking body inserted into the shell and a linking spring arranged between the linking body and the surface of the shell, and the linking body comprises two linking edges extending to a place above the linked edge; and the central button comprises a central pressing body inserted into the linking body and a central spring arranged between the central pressing body and the bottom face of the shell. The linked contact switch structure can be used to link different contact switches.

Description

【Technical field】 [0001] The invention relates to a linkage contact switch structure, in particular to a linkage contact switch structure capable of performing combined operations on different contact switches. 【Background technique】 [0002] Contact switches are push button switches and are widely used in electronic products. see figure 1 , figure 1 It is a side view of the pressing structure of the prior art contact switch. The current common method is to arrange several contact switches 100 on the circuit board 300 of the electronic product, and the housing 400 of the electronic product is provided with buttons 200 corresponding to each of the contact switches 100 one by one. The button 200 can further make the corresponding contact switches 100 be pressed to be in an open state, so as to achieve the operation of the electronic product. [0003] However, each button 200 corresponds to each contact switch 100 one by one, and pressing a certain button 200 can only opera...
