摘要： A potentiometer has a case, a housing, a base and a rotor rotatably arranged in the chamber of housing. The housing is provided with a pair of projections on both side walls thereof and two pair of corner projections at four corners thereof respectively while the case has a pair of bent long legs in which holes are defined to receive the side wall projections of the housing and a pair of bent short walls are arranged to cover the top of the housing. The case may be pushed down upon the housing with the pair of bent long legs thereof being slid down into vertical grooves arranged between the corner projections of the housing until the side wall projections of the housing are slidingly snapped into the holes of the case and thus, the case and the housing may be assembled in one operation. Two end walls of an arcuate portion of a narrow strip are arranged on the surface of the rotor and abut alternatively against two vertical walls of a rectangular strip arranged inside the housing hole and located adjacent a collector element of the base, whenever the rotor rotates in a clockwise or counter-clockwise direction.
