ABSTRACT:
A variable resister includes a housing made of a synthetic resin and having an inner space that opens to an open upper end of the housing, and a substrate made of a synthetic resin mounted on the housing for closing the open upper end of the housing to enclose the inner space. A resister is provided on the surface of the substrate and terminates in a conductive extremity while a conductive terminal electrically connected to a power supply terminates in an extremity that opposes the conductive extremity of the resister in the inner space. A conductive coil spring is elastically disposed between the conductive extremity of the resister and the extremity of the conductive terminal. A contact is disposed in sliding engagement with the resister such that a distance between the contact and the conductive extremity of the resister is used as a control variable.
