Abstract
A switch has a normally-closed fixed contact unit, a common contact unit, a pressing member, and a movable contact that is attached to the pressing member, and that slides on the normally-closed fixed contact unit and the common contact unit. A conductive region and an insulating region are formed on a sliding surface of the movable contact in the normally-closed fixed contact unit in order toward a pressing direction of the pressing member. A conductive region and an insulating region are formed on a sliding surface of the movable contact in the common contact unit in order toward the pressing direction. The movable contact slides from the conductive regions to the insulating regions to switch from a closed state to an opened state.
