AbstractA proximity switch assembly for signalling the location of a movable member at either of opposite end limits of movement relative to a stationary frame includes a compact elongate housing adapted to be mounted on the frame to extend along the path of movement of a power driven member, such as a piston rod, which shifts the movable member between its end limits. A proximity switch is fixedly mounted in the housing and a switch actuating member is mounted for sliding movement over a relatively short distance sufficient to move an actuating tab into and out of actuating proximity to the switch. Lost motion abutment means on the switch actuating member and the power driven member move into engagement with each other as the power driven member approaches each end of its stroke to move the actuating member within actuating proximity to the switch as the movable member arrives at one end limit and to move the actuating member out of actuating proximity to the switch as the movable member arrives at its opposite end limit.
