DEFINITION

Classification: 318/467

(under subclass 466) Subject matter in which two or more means are provided for sensing or determining two or more positions or limits-of-travel of the motor or other device. The systems included herein are "open-loop" controls and thus are not servomechanisms.

(1) Note. For example, a plurality of push buttons may be

provided, each determining a different position or a different limit-of-travel at which the sensing means will function to initiate operation of the motor control means.

(2) Note. A single position or limit-of-travel determining means which is merely adjustable so as to initiate a motor control operation when any of a number of possible positions or limits-of-travel are reached, is not included herein.

(3) Note. Where the system is a closed loop position servomechanism, classification is not herein, but in subclass 600 or 672, above.
