Abstract

The invention discloses a microswitch with a forced separating mechanism, and the microswitch comprises a housing. The interior of the housing is provided with a normally-closed connector assembly anda common connector assembly and also comprises an elastic assembly which is electrically connected with the common connector assembly and can be electrically connected with the normally-closed connector assembly. The elastic assembly is linked with a triggering assembly, and can swing around a supporting part of the common connector assembly under the action of the triggering assembly. The interior of the housing is also provided with the multi-stage transmission forced separating mechanism, and the forced separating mechanism can make contact with the elastic assembly under the action of thetriggering assembly, and can separate the elastic assembly with the normally-closed connector assembly in a forced manner. The microswitch is provided with the forced separating mechanism. When the microswitch has an abnormality and the contact of a static contact of the normally-closed connector assembly with a moving contact on the common connector assembly is not normally cut off, the forced separating part will separate the moving and static contacts in a forced manner, so as to guarantee the electrical safety.

Description

technical field

[0001] The invention relates to a switch, in particular to a micro switch with a forced separation mechanism. Background technique

[0002] The micro switch is a contact mechanism with a small contact interval and a quick-action mechanism, which performs switching actions with a specified stroke and a specified force. It is covered with a casing and has a trigger rod on the outside. Small, hence the name micro switch. The external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.). Tap to quickly connect or disconnect. When the force on the transmission element is removed, the action reed produces a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously. The contact spacing of the micro switch is small, the action stroke is short, the pressing force is small, and the on-off is ...
