Claims

[Claims for Utility Model Registration] (1) A switch that electrically detects the presence or absence of a switch operation and controls the on/off of a switching element such as a transistor based on this detection signal, is a support pin that serves as a lead for the surface electrode of this crystal resonator, a top cover that has an opening on the front surface and holds the crystal resonator between the holding pin on the inner surface of the support pin, and a top cover that is attached to the front surface of this top cover. a touch sheet made of translucent rubber or the like; a crystal holder that holds the support pin via a spring; a case body that is integrated with the crystal holder and the top lid; a printed wiring board connected to a support pin that also serves as a lead and from which a lead wire is drawn out; a light emitting diode as an illumination light source mounted on the printed wiring board; an oscillation circuit mounted on the printed wiring board; The oscillation detection circuit and other components constitute a detection unit that detects the presence or absence of a switch operation.Normally, the oscillation circuit including the crystal resonator is kept in an oscillating state, and when the switch is operated, the touch sheet is pressed to activate the crystal resonator. The surface electrode is brought into contact with the crystal oscillator, and the resulting stop of oscillation is detected and used as a detection signal indicating the presence or absence of a switch operation. An illuminated switch characterized by sandwiching a film and displaying a message by emitting light from a light emitting diode. (2) The illuminated switch according to claim 1, which has been registered as a utility model, in which the surface electrode of the crystal resonator is an opaque electrode, and a required message is hollowed out in the opaque electrode to serve as a substitute for the message film.
