DEFINITION

Classification: 318/673

(under subclass 672) Subject matter in which the discontinuous or "on-off" motor control is part of a "seeking" switch system. A "seeking" switch system is one in which the motor moves the wiper of a multiposition noncoded switch until a circuit which includes the motor and the switch is found which deenergizes the motor.
