ABSTRACT:
A linear potentiometer, having a longitudinal housing with a resistance path and with a wiper guided by a push rod sliding therein. The push rod is supported at its entry into the housing of the potentiometer via a slide bearing which contains an elastic ring element, preferably an O-ring. This ring element embodies the sole connection between a stationary outer bearing and an inner bearing which is movable in a swinging manner relative to the outer bearing because of the elastic connection. The push rod slides in the inner bearing. The inner and outer bearings, by means of opposing annular grooves, receive the elastic ring element connecting them.
