Abstract

The disclosed control device includes an electrical switch having a switch body in which an electrically insulating switch carriage is manually movable along a predetermined path. Fixed electrical contacts are mounted on the body along such path and are selectively engageable by an electrically conductive contactor mounted on the carriage. The contactor takes the form of an angle-shaped plate consisting of first and second flanges in a rectangular relationship. The first flange has portions, preferably contact points, slidably engageable with the fixed contacts. The carriage has a guide slot for slidably receiving the second flange. A compression spring on the carriage produces contact pressure between the first flange and the fixed contacts. The second flange and the guide slot constitute the sole guide and support for the contactor, which is substantially flat except for the contact points. The flanges extend in a direction parallel to the path and have the same length in such direction. The second flange has a detent point projecting laterally into a guiding channel formed in a side wall of the guide slot. The detent point is detained in the guiding channel by a detent bar obstructing the entrance to the channel.
