Abstract
A potentiometer comprises a housing having a resistance element disposed therewithin, a spur gear rotatably housed within the housing and drivingly engaged with a worm gear that is rotatably supported by the housing for rotating the spur gear when such worm gear is externally turned. A resilient wiper assembly carried by the spur gear for rotation therewith sweeps the resistance element and applies a resilient force to the spur gear to urge the latter in a direction away from the resistance element. The spur gear has a toothless area defined at a portion of the toothed periphery thereof which corresponds in position to one end of the resistance element. The toothless area has a tapered face engageable with the worm gear to displace the spur gear in the opposite direction against the resiliency of the wiper assembly when the wiper means is brought to the end of the resistance element wherefore the spur gear can be disengaged from the worm gear.
