Abstract
This invention is a sensor switch capable of sensing the contact by human body, comprising a contact conductor, issuing a signal once a human body touches it; a frequency generator, for the receiving of the signal issued by the contact conductor, converting the signal into a preset frequency to output; and a detecting circuit, for the receiving of the signal issued by the frequency generator, determining if the output frequency of the frequency generator is changed and issuing an electric signal subject to the frequency that is detected. Accordingly, once a human body gets in contact with the contact conductor, the detecting circuit will issue an electric signal to form a sensor switch.
