DEFINITION

Classification: 234/87

(under subclass 79) Device including means responsive to actuation of the sensing means to initiate or terminate the transmission of force from a power drive train for moving an interposer* from one of its two (effective, ineffective) positions to the other position.

(1) Note. Typical mechanism is illustrated in Fig. 17, wherein the progressively advance pattern P is sensed by a contact brush to control a circuit for the positioning magnet of an interposer I. [figure] [caption]Fig. 17 SENSER CONTROLS POWER TO MOVE INTERPOSER (subclass 87).
