Abstract
A self-adjusting electric tappet switch includes a slider linearly guided in a housing for activation or closure of one of several electrical contacts and a tappet which is selectively rotatable relative to the slider for adjustment of the travel limit of the switch. The slider has a first engagement portion provided with engagements parts, and the tappet includes a corresponding second engagement portion having an oblong cross-section provided with spaced apart circumferential grooves. The switch is self-adjusted by relative rotational movement between the slider and the tappet to lock the pair together. In an installation and adjustment position of the tappet and slider system, the slider is held in a predetermined fixed switching position in the housing to permit relative longitudinal slidable movement between the tappet and the slider for adjustment of the tappet without causing any movement of affecting the position of the slider within the housing. After the length of the tappet and slider is set, are locked together by relative rotation therebetween. Displacement of the tappet within the housing causes a corresponding movement of the slider thereby carried on the tappet within the housing relative to the electrical contacts.
