Abstract
Abstract A slide potentiometer comprising a housing having a printed circuit board positioned in an interior compartment formed therein. An elongated resistance element is provided on one side of the circuit board and has a pair of terminals electrically connected to the opposite ends thereof. An elongated collector element is positioned on the one side of the circuit board in a parallel spaced apart relationship to the resistance element. A third terminal is electrically connected to the collector element. A wiper block is slidably mounted in the interior compartment of the housing and has a pair of electrically connected wiper elements which slidably electrically contact the resistance element and the collector element. The wiper block is provided with an actuator element which extends upwardly therefrom. A cover is secured to the housing and extends over the upper end thereof and has an elongated slot formed therein which receives the actuator element extending therethrough. A knob or the like is secured to the upper end of the actuator element to permit the wiper block to be selectively slidably moved relative to the resistance element and the collector element. A modified form of the potentiometer is also disclosed wherein a second wiper block is slidably mounted in the interior compartment of the housing on the opposite side of the circuit board and which is in electrical contact with a second resistance element and a second collector element provided on the other side of the circuit board. Each of the embodiments includes means for maintaining the wiper blocks in electrical engagement with the resistance element and the collector element.
