Abstract
A switch comprises a seat, a key body, a first elastomer, a second elastomer, and a cover. A neck portion of the key body has an assembling portion, and the assembling portion is installed with the light generator. As the key body is pushed, the second elastomer will contact the cover; the positive (negative) power connected to a conductive piece will be transferred to the positive (negative) end of the light generator. At the same time, the first elastomer contacts internal wires of a first receiving portion so as to provide negative (positive) power to the negative (positive) ends of the light generator. Then, electric signals are outputted and the light generator lights up.
