ABSTRACT:
A switch unit contains a case; a fixed contact members disposed on a bottom wall of the case; conductor plates rockably disposed on the bottom wall; driving bodies disposed on the conductor plates in a rotatable state in which the elevating movement thereof is allowed; a plate spring member for resiliently biasing the driving bodies; and a cover member for covering an upper opening of the case. The driving bodies are provided with pressed parts that protrude above the cover member. When the pressed part is driven to rotate laterally by the rocking operation of the operating knob, the driving body rotates, which causes the conductor plate to slide on the bottom wall. As a result, the switch unit is switched to its ON state.
