Problems solved by technology

[0003] In addition, the internal structure of the existing shrapnel switch is complicated and chaotic, and the shrapnel is easy to loosen and bounce off, which greatly affects the performance of the switch. At the same time, its sensitivity is poor and cannot achieve an accurate sensitivity level. Therefore, it is necessary to design a safe, simple structure and Responsive dome switch

Abstract

The invention discloses a spring plate switch comprising a switch housing and a key. A fixed seat is arranged at the right side of the switch housing; fixed screw holes are formed in the fixed seat; a normally-open wiring terminal is arranged at the upper end of the fixed seat; a normally-closed wiring terminal is arranged at the lower end of the fixed seat; and contact spring plates are arranged at the left sides of the normally-open wiring terminal and the normally-closed wiring terminal. An electrified spring plate is arranged at the middle of the fixed seat; and a copper bead is arranged at the left end of the electrified spring plate. A clamp seat is arranged at the left end of the switch housing. The key is arranged at one side of the switch housing and is fixed with the switch housing; a support block is arranged below the key; a fixed block is arranged above the support block; and a thin spring plate is arranged on the fixed block. A rotating shaft and a spring are arranged below the support block; and the rotating shaft penetrates the spring. The spring plate switch has advantages of safety electrification, simple structure, and sensitive reaction.

Description

technical field [0001] The invention relates to a shrapnel switch.
