PROBLEM TO BE SOLVED: To prevent the simultaneous operation of a plurality of switch contacts with a simple structure. SOLUTION: This switch device 1 is provided with a framework 41, a knob holder 21 supported by the framework 1 freely to swing, and a knob 31 to be slid in a pushing direction in relation to the knob holder 21 on the basis of the pushing operation. A switch contact 54 is pushed in response to the pushing operation of the knob 31 to push a switch contact 53 in response to the swing of the knob holder 21 with the pushing operation of the knob 31. The switch device 1 is provided with a projection part 35 provided in the knob 31 and a guide mechanism G1, which is provided in the framework 41 and provided with a guide groove 44b for guiding movement of the projection part 35 in the pushing direction and a lock surface 44a provided in the top surface of a guide rib 44c for locking the projection part 35 on a guide start part side of the guide part 44 when the knob holder 21 swings to hinder movement of the projection part 35 in the pushing direction in relation to the guide part 44.
