Abstract
A slide-type switch for controlling electrical output to a light or motor. The switch includes a printed circuit board having a sliding variable resistor mounted thereon. When the variable resistor is adjusted for minimum current flow, the slide on the variable resistor comes into contact with an actuator arm also mounted on the printed circuit board. The actuator arm then becomes detached from a butt contact, breaking the circuit. A novel knob arrangement is also disclosed for use with standard all face plates.
