A button-less push switch board including a plurality of push switches which comprises an insulator plate having a plurality of penetrating holes, a transparent flexible cover sheet overlying the main surface of the insulator sheet and having identification marks printed thereon to indicate the positions and functions of the switches, and a printed circuit plate on the reverse surface of the insulator plate and having fixed contacts formed thereon. A transparent block is disposed in each hole of the insulator plate and is urged towards the cover plate by elastic members supported thereon. Each elastic member is of cup-like shape and has a movable contact corresponding to a pair of fixed contacts on the printed circuit plate. A lamp or a light emitting diode is disposed in each hole of the insulator plate and is mounted on the printed circuit. Each fixed contact and each lamp or light emitting diode are connected to an external control circuit.
