Abstract
A multiple position power control switch is connected in series with a load across a power source. A five position rotary switch permits the load to be selectively operated at four different power levels. The fifth position of the switch provides 'OFF' operation. With the invention, component cost is reduced and power level control of a load is achieved with minimum power dissipation.
