Micro-switch employing lever principle

A micro-switch employing lever principle, comprising:

• a housing including a housing compartment inside, at least one conductive terminal and a common terminal extended outwards from the housing compartment, and an actuation member coupled with the common terminal;
• the actuation member including a butting portion at one side of the common terminal and a connecting portion at another side of the common terminal, the connecting portion including a first conductive state connecting to the conductive terminal and a second conductive state not connecting to the 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 driven member which is located between the press member and the actuation member and includes a pivotal portion hinged on the housing in a swivelable manner, a force-receiving portion opposite to the pivotal portion in the displacement and a force-applying portion driven by the force-receiving portion to move about the pivotal portion serving as a fulcrum, the force-receiving portion being depressible by the press member to drive the force-applying portion to press the butting portion so that the butting portion then drives the connecting portion to switch between the first conductive state and the second conductive state.
