Claim Text:
1. A switch comprising: a normally-closed fixed first contact unit; a second contact unit; a pressing member; and a movable contact that is attached to the pressing member, and that slides on the first contact unit and the second contact unit, wherein a first conductive region and a first insulating region are formed on a first sliding surface, on which the movable contact slides, in the first contact unit, wherein the first conductive region is arranged before the first insulating region in a pressing direction of the pressing member, wherein a second conductive region and a second insulating region are formed on a second sliding surface, on which the movable contact slides, in the second contact unit, wherein the second conductive region is arranged before the second insulating region in the pressing direction, wherein the movable contact slides from the first and second conductive regions to the first and second insulating regions to switch from a closed state in which conduction between the first contact unit and the second contact unit is established, to an opened state in which conduction between the first contact unit and the second contact unit is cut off, wherein a first boundary between the first conductive region and the first insulating region in the pressing direction is offset in the pressing direction from a second boundary region between the second conductive region and the second insulating region in the pressing direction.
