Abstract
A potentiometer contained within a housing is operated from the outside by means of an operating member which extends inward through an orifice in a housing wall. The operating member engages the potentiometer drive stem with the aid of an O-ring slip clutch, and includes a flange which is spring-urged against the interior housing wall to inhibit internal explosions from propagating to the outside.
