The Series DSS Direct-Contact Speed Switch is a compact switch

designed to include all mechanical and electronic components in one

housing. It will produce an output signal at a predetermined speed which

may be either over-speed, under-speed or zero-speed. Rugged, heavy-

duty construction combined with solid state electronics and photo-elec-

tric technology makes this one of the most advanced motion detectors

available. Series DSS protects all valuable rotating equipment including

belt conveyors, bucket elevators, rotary feeders or screw conveyors. It

operates in a clockwise or counter-clockwise direction and mounts in

any position.
