Push-button switch device |
摘要 |
A switch unit receive an AC signal and includes first and second push-button switches and at least one rectifying diode. Each of the first and second push-button switches is a 2-stage switch or a 3-stage switch. The first and second push-button switches and the at least one rectifying diode are configured such that the switch unit selectively generates any one of a non-signal, a positive half-wave rectified signal, a negative half-wave rectified signal and a full wave alternating signal to each of first and second outputs. The first and second outputs of the switch units are transmitted to an output unit by way of two transmission wires, respectively. The output unit discriminates the switching state of the first and second push-button switches based on the signal received from the switch unit via the two transmission wires.
