Abstract: A variable resistance control comprises a resilient nonconductive annular skirt sandwiched between a pair of substrates. The skirt has an arcuate section and a pair of posts interconnected by a bridge section. Each of the substrates comprises a circular portion carrying a resistance film and an extending portion provided with apertures and engaged by the posts. A driver is rotatably carried by the control and contactors are constrained to rotate with the driver wipingly engaging the resistance films. The apertures in the extending portions of the substrates are in line with the posts and the periphery of the bridge section substantially coincides with edges of the extending portions. Terminals are secured to the extending portions of the substrates and comprise a head and a tail. The head is received in an aperture and a pair of spaced fingers integral with the terminal are clinched into engagement with the head disposed between the spaced fingers.

Abstract: A variable resistance control containing a one-piece stamped mounting bracket having an integral collector ring for positioning a rotatable gear and having a pair of integral yokes for aligning a lead screw in driving relationship with the rotatable gear. A contactor constrained to rotate with the gear wipingly engages a resistance element. Each of the yokes comprises a pair of arms arcuately clinched around the lead screw to secure the lead screw to the mounting bracket. Integral with the gear are two outwardly extending resilient fingers for engagement with a respective one of the yokes to arrest rotation of the gear. Continued rotation of the lead screw after rotation of the gear has been arrested flexes the resilient finger toward the lead screw for driving the gear out of engagement with the lead screw. An aperture is provided in the lead screw for insertion of a shaft or tool for remote actuation of the control or for actuation of another control.
