Abstract
A motor control system utilizes a low cost switched controller for provding operator initiated control signals. The controller has therein a pair of switches which together define four possible modes of operation, depending upon operator manipulation of the controller. These four modes cause the system to either stop the motor, decrease the speed of the motor, maintain the speed of the motor constant, or increase the speed of the motor.
