ABSTRACT:
A power control device utilizing a circular control potentiometer having a rotatable control shaft may be adapted to a slide switch configuration by attaching a pinion gear to the shaft. A slide bar having a rack member for engagement with the pinion gear may then be utilized in place of the knob typically utilized with the shaft. The fins of the heat sink associated with the power control device advantageously act as guide channels for the slide bar. A cover member having a slot adapted to accept the slide bar handle fits over the slide bar and heat sink, acting as a retainer for the slide bar and providing a chimney effect for the heat sink.
