ABSTRACT:
A proximity switch has a switching body with a sensing area which is parallel to a mounting base securable to a support area. The sensing area is adjustable longitudinally towards a target area on an axis normal to the sensing area and the support area by being adjustably securable to a longitudinal mounting stud. The stud and switching body may have interengaged threads for adjustment, with the stud rotatable or fixed. The stud also may be substantially smooth, with the switching body adjustable longitudinally by a slotted expansible stud, or by pins engageable with a longitudinal series of holes.
