ABSTRACT:
A self-adjusting electric tappet switch includes a housing, an electrical switch contact carried on the housing, a slider member movable relative to the housing and adapted to actuate the electrical switch, and an elongate tappet member extending from the housing and selectively engageable with the slider member. The slider member has a first engagement portion adapted to selectively connect with a second engagement portion provided on the elongate tappet member. The switch is self-adjusted by relative rotational movement between the slider member and the elongate tappet member to lock the pair together. In an installation and adjustment position of the tappet and slider system, the slider member is held in a predetermined fixed switching position in the housing relative to the electrical switch while relative longitudinal slidable movement between the tappet member and the slider member is enabled for adjusting the tappet relative to the slider member and switch housing without affecting the position of the slider member within the housing. After the desired length of the tappet member is selected, the slider and tappet members are locked together at the first and second engagement areas. Afterwards, displacement of the tappet member within the housing causes a corresponding movement of the slider member carried on the tappet member relative to the electrical switch.
