Abstract
A pivoted power controller in its limit positions engages a switch operating element to shunt or open a power control circuit through switch contacts mounted on a circuit board. A resistive element mounted in the same circuit board is engaged by a wiper on the controller during travel between its limit positions to vary the power supplied to a load. The resistance of the resistive element may be adjustably varied by a trimmer mounted on the circuit board adjacent one end of the resistive element.
