A plurality of p anode regions are formed at one surface of an n\u2212 substrate. In accordance with the preferred embodiment of the present invention, a photo-sensitive layer is formed over a substrate, followed by the formation of a photo-insensitive layer over the photo-sensitive layer. The pivot portion comprises a ready position and an operative position, the pivot portion being adjustable from the ready position to the operative position via relative movement with respect to the body portion. The other end of the drive shaft extends through the housing to a cam, located with a distal end of the drive shaft housing.
