Abstract
An improved press switch for channeling signal transmission or output includes a body, two terminal element mounted on the body, a first elastic element located in the body, a press element disposed in the body above the first elastic element, and a face panel for covering the body at the front side thereof. When the press element subjects to an external pressing force, a second elastic element will be driven to press the first elastic element which in turn makes contact with the two terminals for establishing an electrical link to output electric characteristics desired. When the external pressing force is released from the press element, the innate elastic force of the first and second elastic element will push the press element to its original position.
