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.
