The GEM KFLS Flat-Plate Hoists Limit Switch comes with a bracket to mount to a flat plate hoist and it counts the rotation of the gear. Limit switches used with a Gem Remote model ending in an “A”. This denotes auto stop capabilities in the remote. Previously wired for auto stop capabilities but only have this capability when used with the correct Gem Remote. Switch mounts to front of the flat plate hoist using the existing bolts that attach the worm housing to the plate. Hoist must be mounted so the drive pipe is coming out of the back of the hoist. The GEM Remotes: KFLS Limit Switch Wiring Diagram will give you all the information needed to wire your own switch. Ships directly from BH-USA.
