ABSTRACT:
A rotary potentiometer is provided with a switch, preferably as a final control element for the control of electrical machinery. An enclosed, prefabricated rotary potentiometer component with its own casing is inserted in a cup-shaped upper casing that is open on one side. Switching contact supports are housed in the upper casing by means of peripheral wall sections. These contact supports are actuated by a cam actuating member that is mounted on a fulcrum pin so as to permit play and simultaneously also effect rotation and retention of the potentiometer component in the upper casing.
