WIPO Patent Application WO/2020/019359

A1

The present invention relates to a micro switch, and relates in particular to a micro switch used for a location signal device of a breaker and a location signal device of a breaker using the micro switch. A micro switch used for a location signal device of a breaker, wherein the micro switch is provided with a housing and a moving sheet, the housing is provided with a contact, an end of the moving sheet is connected to the housing, the connection position between the moving sheet and the housing acts as a pivot for movement, and when the moving sheet is pressed, the moving sheet is pressed down to touch the contact; a free end of the moving sheet is V-shaped or semi V-shaped; top and bottom sides of the housing of the micro switch are provided with insulating gaskets. The present invention solves the problem wherein the reliability of signal feedback is low due to a micro switch easily being touched by mistake when isolation and test distances are small, and also solves the problem wherein the requirements for the precision of drawer trilocation is high.
