ABSTRACT:
Disclosed is a variable resistor of a simple construction having a driving mechanism, which can be assembled with ease and which allows contactors movable by an operation lever to be normally held in a predetermined position on a resistance element. The lever can be forcibly moved to vary the output of the resistor, and yet the lever will be returned automatically to its original position when the lever is released from the force exerted thereon.
