PROBLEM TO BE SOLVED: To enable to use parts of common specifications for a first and a second compression springs and reduce cost by preventing fusion of one movable contact and a fixed contact and by installing level difference between a first and a second faces. SOLUTION: The switch is equipped with the first to third movable contacts 211-231, the first to third fixed contacts 212-232, a driven part 11, and the first to third compression springs 301-303. The first to the third movable contacts 211-231 are respectively connected to and disconnected from a prescribed direction 91. The driven part 11 is installed on the opposite side to the first to third fixed contacts 212-232 against the third movable contacts 211-231, and has the first to third faces 11a to 11c on the first to third movable contacts 211-231 side. Between the first face 11a and the second and the third faces 11b, 11c, level difference is installed. The first to the third compression springs 301-303 are respectively extended along a prescribed direction 91, and connects the first to third movable contacts 211-231 and the driven part 11.
