To provide a switch that is mainly used for operating various electronic equipment and a switch device using this with a simple constitution and capable of sure operation.
Since the switch 16 is constituted by housing a nearly coil-form movable contact 15 in an operating part 14A of an elastic sheet 14, placing the outer peripheral contact part 15A of a large diameter of the movable contact 15 on the outer peripheral fixed contact 13 of the substrate 11 upper face, and making the center contact part 15B of a small diameter opposed to the center fixed contact 12 with a prescribed gap, the switch 16 can be formed by a simple and easy constitution. By a spring load of the nearly coil-form movable contact 15, the switch and the switching device using this capable of the sure operation without a catch or the like can be obtained.
