Abstract
A switching device has employed a linearly operating variable resistor in place of the rotatively operating variable resistor. The switching device comprises a guide shaft and an operating knob rotatably slidably mounted thereon. The knob has an actuating arm extending from the guide shaft which mates with a longitudinal groove of a contact holder. The contact holder is movable between a first and second position by rotation of the operating knob about the guide shaft. An operating element linearly movable relative to the axis of the guide shaft, is mated with the operating knob to move the operating element to selectively adjust the variable resistor.
