Abstract
A pushrod switch having a plastic switch housing, a pushrod with a plurality of peripheral teeth arranged in the switch housing, a movable sliding member contained within the switch housing and provided with opposing teeth engagable with the pushrod peripheral teeth and a locking catch device for releasably fixing the pushrod relative to the sliding member. The locking catch device includes two guide elements located in the sliding member and each shaped like a quarter shell; each have interior curved surfaces facing each other provided with the opposing teeth. The guide elements extend in longitudinal directions parallel to each other, are located on opposite sides of a longitudinal central plane extending vertically through both the sliding member and the pushrod, are located on opposite sides of a horizontal transverse central plane passing through the pushrod and rotated about 90.degree. from the plane so as to be diagonally across from each other in the sliding member, and have longitudinal edges parallel to the plane. The guide elements are located in the sliding member so that it is possible to make the sliding member in a single piece by a two-piece injection mold, whose mold halves meet at a vertical longitudinal central plane of the sliding member and have shaping elements. The halves are formed so one shaping element forms the set of opposing teeth on the upper guide element and the other shaping element forms the set of opposing teeth on the lower guide element.
