ABSTRACT:
A control device includes a magnetically actuated responder and an actuator. The responder is fixed to a relatively stationary portion of an apparatus and the actuator is fixed to a portion of the apparatus which is movable relative to the fixed portion. The fixed portion includes a housing for constraining the second, movable portion to linear movement. The actuator is located so that its outer surface is recessed into the surface of the movable portion flush with the surface of the movable portion of the apparatus thus providing an actuator for the responder which does not interfere with the movement of the movable portion. An alternate embodiment contemplates the use of a plurality of flush-mounted actuators axially spaced along the movable member with each actuator occupying only a portion of the circumference of the movable portion. A plurality of corresponding responders are located about the circumference of the movable portion for actuation by the actuators in response to the movable portion of the apparatus reaching predetermined positions relative to the fixed portion of the apparatus.
