Abstract

The application provides a micro switch. The micro switch comprises a shell, a moving contact and a static contact which are arranged in the shell, and a reset magnet. The moving contact is a first magnet, and the first magnet moves towards the side close to the static contact under the action of the closing force so that the moving contact point of the moving contact is connected with the staticcontact point of the static contact. The reset magnet is arranged in the shell and is used for applying a magnetic field force for resetting the first magnet to the first magnet. After the closing force is removed, the first magnet resets under the action of the magnetic force, so that the moving contact point is separated from the static contact point. In the scheme, the moving contact, the static contact and the reset magnet will not deform and will not generate fatigue stress due to deformation in the connection and separation processes of the moving contact point and the static contact point. Therefore, compared with the mechanical micro switch in the prior art, the micro switch has a longer service life and better sensitivity and hand feel of touch.

Description

technical field [0001] The present application relates to the technical field of switches, in particular to a micro switch. Background technique [0002] Existing micro switches usually use a mechanical structure to achieve power on and off. For example, the conductive part is an arc-shaped metal shrapnel. The metal shrapnel is elastic. Under the action of an external force, the metal shrapnel can be pressed down and produce a conductive The relative displacement of some electrical contacts, at this time, the micro switch is turned on. When the external force is removed and the metal shrapnel resumes its deformation, the metal shrapnel is disconnected from the conductive part, and the micro switch is turned off, thereby realizing the control of the circuit. [0003] However, for mechanical micro switches, the metal shrapnel will generate fatigue stress after being pressed many times, which will cause physical permanent damage after reaching a certain limit, and the service ...
