Lock switch, especially motor-vehicle door-lock switch

摘要

What is described is a lock switch, especially motor-vehicle door-lock switch, which can be actuated by control cams on a cam track of a lock cylinder and which has two pairs of snap-action switch contacts which are arranged next to one another and which can be switched individually, via a common rotatably mounted actuating member, in dependence on the direction of adjustment of an actuating-member tappet part loadable by the control cams. To improve the switching accuracy in the light of the production tolerances occurring on the lock switch, the tappet part is provided with a convex rounding at its end loadable by the control cams. The control cams likewise have a convex rounding merging by way of a concave rounding into the cam track of the lock cylinder.
