<P>PROBLEM TO BE SOLVED: To provide a switch device capable of having insulation between contacts even when made compact. <P>SOLUTION: A switch device 1 includes an operation part 11 which is rotated around an operation shaft 13h as an axis, a movable contact 12 provided to the operation part 11 in one body, a fixed contact 13 contacting and leaving the movable contact 12, and a case 14 having a storage part 14a which houses a part of the operation part 11, the movable contact 12, and the fixed contact 13. The fixed contact 13 comprises a common contact 13a and a plurality of changeover contacts 13b, and is characterized in that a common contact part 13i of the common contact 13a that the movable contact 12 slides on and a changeover contact part 13l of the changeover contact 13b that the movable contact 12 slides on are arranged on different concentric circles having their centers at the operation shaft 13h, the common contact part 13i is arranged on a concentric circle farther from the operation shaft 13h than the changeover contact part 13l, and an outer connection part 13o of the common contact 13a which can be electrically connected to the outside is arranged between an outer connection part 13p and an outer connection part 13q of the changeover contact which can be electrically connected to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
