Abstract
A contact switch aims to reduce damages caused by electro-static discharge and facilitate depressing operation. It includes a casing which has a housing compartment for holding a first contact leg. The first contact leg has a first anchor flange and a second anchor flange projecting in the direction of a depressing opening. A micro mechanism is located at a lower position to increase the electro-static discharge. Due to the lower position of the micro mechanism, a retaining section may be formed by extension to space from the first anchor flange to form a depressing space so that a pushbutton may be moved therein without skewing to establish secured electric connection of the contact switch.
