Abstract: An electrical switch including a toggle lever pivotally mounted to a switch housing with the toggle lever connected to a slide in a manner to provide longitudinal motion to the slide between a first and second end positions when the toggle lever is pivoted. The slide includes a first conductor, which when the slide is at the first end position, maintains contact with a first conductive track and, when the slide is at the second end position, provides an electrical conduction path between the first conductive track and a second node. When the slide is located between the first and second end positions, the first conductor provides an electrical conduction path between the first conductive track and a third node. The first conductor is also in contact with a second conductor within the slide and the second conductor is in sliding contact with a circuit contained upon a substrate which is further connected between the first and third conductive track and having an output connected to the second conductive track.

Abstract: An improved compact electronic switch for controlling an electric motor comprising a housing into which a trigger actuator reciprocates for selecting motor speed and a reversing switch mounted on the housing and interlocked with the trigger actuator for selecting motor direction. Improvements include; an improved switch contact arrangement which reduces arcing on switching from full power to variable power motor control, an improved printed variable resistor for the electronic speed control circuitry, and an improved and simplified reversing switch unit.
