Mouse microswitch

Abstract

The invention provides a mouse microswitch, which comprises a base and a housing, wherein the base and the housing are fastened to each other; a hollow cavity is formed between the base and the housing; a movable spring sheet and a clamping part are arranged in the hollow cavity; the clamping part comprises a lower terminal and a fixed terminal; the lower terminal and the fixed terminal are L-shaped; the vertical parts of the lower terminal and the fixed terminal pass through the base and extend downwards to form fixed pins; a fixed contact is arranged at the horizontal part of the lower terminal; one end of the movable spring sheet is clamped with the horizontal part of the fixed terminal and the other end extends to the upper part of the fixed contact towards the left; and the movable spring sheet is extruded, slides downwards and is conducted with the fixed contact to form a conduction line. The mouse microswitch is simple in structure and miniaturization production of the microswitch is facilitated.

Description

technical field [0001] The invention relates to the field of micro switches, in particular to a mouse micro switch. Background technique [0002] Generally, the mouse micro switch has a moving shrapnel and a lower terminal. When the mouse micro switch is clicked, the moving contact on the moving shrapnel will rub against the fixed contact on the lower terminal, causing the circuit to send an electrical signal to the computer. Then reset. Under all the buttons on the mouse, there must be a micro switch or a tact switch, so in fact the micro switch is the button of the mouse. The function of the button on the mouse shell is just to facilitate the user to press the micro switch. Not only for the mouse, but also for various other toys. [0003] With the continuous development of society and people's requirements for the miniaturization of the mouse, the micro switch in the mouse will inevitably change accordingly, and the traditional large micro switch is no longer suitable fo...

AI Technical Summary

Problems solved by technology

[0003] With the continuous development of society and people's requirements for the miniaturization of the mouse, the micro switch in the mouse will inevitably change accordingly. The traditional large micro switch is no longer suitable for the development needs of the market.

At the same time, due to the frequent use of the mouse, the fixed contacts on the lower terminal will be greatly worn, which will cause the micro switch of the mouse to fail and affect the service life of the product

In the prior art, the fixed contact is fixed on the lower terminal and cannot be disassembled. After the fixed contact is worn out, the micro switch must be replaced, which reduces the service life of the micro switch
