ABSTRACT:
In a switch device, slide plates slide on a microswitch casing independently from each other. When one of the slide plates is slid in a left-hand side direction from its neutral position against a biasing force of a spring, a cam portion thereof depresses an actuator by a predetermined constant amount putting a corresponding microswitch mechanism into an ON state. Similarly, when the other slide plate is slid in a right-hand side direction from its neutral position against a biasing force of the spring, a cam portion thereof depresses another actuator by a predetermined constant amount to put a second microswitch mechanism into an ON state. Each slide plate is operatively, selectively held through a solenoid device at that position where its cam portion depresses the corresponding actuator.
