Slide-type potentiometer

摘要

A slide-type potentiometer for speed control of electric motors under control of a foot-pedal actuator mechanism comprising an actuating rod reciprocatably movable in the longitudinal directions thereof, a spring member for urging the actuating rod in one of the longitudinal directions, a contact supporting member having an electrical contact secured thereto and mounted on the actuating rod so as to be movable in the longitudinal directions along with the actuating rod, a resistor element positioned such that the electrical contact member is slidably moved on the resistor element upon movement of the actuating rod, and a housing for enclosing the contact supporting member and the resistor element, the housing has a through-hole through which one end portion of the actuating rod extends outwardly.
