Micro-switch provided labor-saving switching

摘要

A micro-switch provided labor-saving switching comprises a housing, a press member located on the housing, an actuation member located in the housing and a driving assembly located between the press member and actuation member. The press member is depressed to move reciprocally in the housing in a displacement. The driving member includes a force-bearing member hinged swivelably on the housing and at least one transmission member swivelable inversely against the force-bearing member. The force-bearing member includes a force-receiving portion in the displacement and an actuating portion connected to the force-receiving portion. The at least one transmission member includes a driven portion driven by the actuating portion and a force-applying portion connected to the driven portion. The driving assembly drives the actuation member through a lever principle to switch between a first conductive state and a second conductive state.

1. A micro-switch provided labor-saving switching, comprising:
a housing including a housing compartment, at least one first conductive terminal and a common terminal extended outwards from the housing compartment, and an actuation member coupled on the common terminal, the actuation member including a butting portion close to the common terminal and a connecting portion remote from the common terminal, the connecting portion including a first conductive state connecting to the at least one first conductive terminal and a second conductive state without connecting to the at least one first conductive terminal; a press member which is located on the housing and depressible to move reciprocally in a displacement inside the housing between an original position and a pressed position; and a driving assembly which is located between the press member and the actuation member, the driving assembly includes a force-bearing member hinged on the housing in a swivelable manner and at least one transmission member hinged on the housing and being swivelable inversely against the force-bearing member, the force-bearing member including a force-receiving portion located in the displacement and an actuating portion connected to the force-receiving portion, the at least one transmission member including a driven portion driven by the actuating portion and a force-applying portion connecting to the driven portion, the force-receiving portion being pressed by the press member to drive the force-applying portion swiveling inversely to press the butting portion so as to drive the connecting portion to switch between the first conductive state and the second conductive state.
