Abstract

The invention provides a microswitch. The microswitch comprises a bottom casing, an upper cover as well as a micro-mechanism arranged between the bottom casing and the upper cover, wherein the micro-mechanism comprises a common terminal, a normally-closed terminal, a normally-open terminal and an elastic piece, one end of the elastic piece is fixedly connected with the common terminal, the other end of the elastic piece is arranged between the normally-closed terminal and the normally-open terminal, the elastic piece is connected with the normally-closed terminal in a normal state, and a button device is arranged at the upper end of a position where the elastic piece and the common terminal are connected. The microswitch comprises a few components, the structure is simple, the production cost is greatly reduced, all the components are in close fit by the aid of simple and precise components and the ingenious design, the sensitivity is high, and the service life is long.

Description

technical field [0001] The invention relates to a micro switch. Background technique [0002] The micro switch is a fast-acting mechanism with a small contact interval. The industry has high requirements for the sensitivity of the micro switch. However, many current micro switches have complex structures and do not improve much in sensitivity. Therefore, proposing a micro switch with simple structure and high sensitivity is an important problem to be solved at present. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a micro switch with simple structure and high sensitivity. [0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a micro switch, including a bottom case and an upper cover, and a micro-motion mechanism arranged between the bottom case and the upper cover, the micro-motion mechanism includes a common terminal, Norma...
