ABSTRACT:
A variable resistance control comprising a variable resistance control portion and a stabilizer assembly portion. The variable resistance control portion is provided with a housing, a resistance element and a contactor supported within the housing with the contactor wipably engaging the resistance element, and an adjustment member operatively connected to the contactor and exposed on the exterior of the housing. The stabilizer assembly portion comprises a stabilizer having weight greater than the weight of the variable resistance portion and having a threaded bushing. An aperture extends through the stabilizer and the bushing and an extension shaft is rotatably received in the aperture with one end extending outwardly from the aperture cooperatively engaging the adjustable member. A U-shaped plate having a bight portion and a pair of arms secures the stabilizer to the housing. The bight portion is provided with an aperture within which the threaded bushing is received and the arms extend and crimpingly engage the housing. The stabilizer and the housing are each provided with coplanar engagement surfaces.
