ABSTRACT:
A variable resistor of modular design having a hub-flange and at least one housing frame having a central opening. A spring carrier provided with a contact spring is arranged in the central opening of the housing and is rotatable by means of an actuation shaft. A carrier plate, on which the resistor course and the collector course are mounted, is positioned adjacent the spring carrier such that the contact spring provides an electrical connection between the resistance and the collector courses. The housing frame has a pot-shaped front side for receiving a rotor. Means is provided for arresting rotation of the rotor to within predetermined angular limits, and the rotor has a contoured rim for engaging a click-stop device.
