ABSTRACT:
A variable resistance slide control includes a housing having a front wall and having a side wall that is integral therewith. A dielectric base having a resistance element and a collector member mounted thereon is secured to the housing in spaced parallel relationship to the side wall. A contactor member engaging the resistance element and collector member is constrained to move with a slider that includes a handle portion projecting outwardly of the housing through an elongated slot which is defined by the front wall and the base. The slider includes a slider block portion with a guide groove therein interfitting with a longitudinal rail that is integral with the dielectric base, and the slider block portion slidably engages an inner surface of the side wall. A second rail is integral with the dielectric base and includes a guide surface that is slidably engageable with the slider block portion.
