ABSTRACT:
There is provided a switching device in which the interval between a normal-close contact and a normal-open contact and the positions thereof can be arbitrarily set without any constraint of a common contact, and which can perform circuit switching at a desired timing. In the switching device, mounted on an inner bottom plane of a wafer is a common contact on which a good conductive return spring electrically connected to a movable contact for urging a slider in the direction reverse to the depressing direction is laid. A normal-close contact and a normal-open contact are arranged side by side on an inner wall of the wafer, and a resilient piece of the movable contact is in slidable contact with the inner wall.
