PROBLEM TO BE SOLVED: To enable a change of the structure between a lock type device and a non-lock type device, with a change of the minimum number of part items by placing a controlled member in a place of a movable contact piece of a pair of switch units inside the two pairs of switch units, which are respectively formed of a fixed contact, a movable contact and a movable contact piece. SOLUTION: A device is provided with a first and a second movable contact pieces 20, 21, a notch parts 20a, (21a), a cut and standing piece part 20b, (21b), first fixing contact points 7a, 7b and a contact part 20c, (21c) to be connected and separated to/from a second fixed contact. A driving rod 6, (6) on the top surface of the first and the second movable contact pieces 20 (21) is pushed for contact, and while performs the drive. The movable contact piece 20, (21) is housed in a housing unit 23, (23) so as to perform a change between a lock type switch and a non-lock type switch. On the other hand, a lock type sea-saw switch device can be obtained by placing a controlled member in a place of the movable contact piece 20, (21) so as to be fitted to the housing unit 23 for fixation.
