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 field of switching technology, and in particular, a micro switch is related to a micro switch. Background technique [0002] The existing micro-switch is usually used to achieve a transient electricity, for example, the conductive portion is an arc-shaped metal shrapnel, and the metal shrapnel has elasticity. Under external force, the metal shrapnel can be depressed, and generates and conductive A relative displacement of partial electrical contact, at this time, the micro switch is turned on. When the external force is removed, the metal shrapnel resumes deformed, and the metal shrapnel is disconnected from the conductive portion, and the micro switch is broken, thereby implementing the control of the circuit. [0003] However, for mechanical micro switches, the metal shrapnel can cause fatigue stress to cause a certain limit, which can cause a physical permanent damage and a short service life.
