Patent ID: 6903293

Claim:
A switch device comprising: a case having a bottom wall and an upper opening, two sets of switch elements assembled to the case; a spring member for applying a returning force to the two sets of switch elements; and a cover member for covering the upper opening of the case, wherein the switch elements include fixed contact members exposed on an inner wall surface of the case, conductor members disposed in the case and capable of being brought into contact with or separated from the fixed contact members, and rotatable driving bodies for driving the conductor members, wherein pressed parts are respectively provided in the driving bodies so as to protrude above the cover member, and opposite pressing forces are respectively applied to the pressed parts of the two sets of switch elements, and wherein, during operation, the driving bodies are driven to rotate via the pressed parts so that the conductor members are brought into contact with or separated from the fixed contact members, thereby allowing any of the two sets of switch elements to selectively perform a set of opening and closing operations, and as the pressing forces are released, the driving bodies are returned to non-operating positions.
