  • Rotary Limit Switch

    Gemco manufactures a complete line of geared rotary limit switches (RLS) that provide upper, lower and/or intermediate limits for moving machinery and mechanisms. When motion is expressed in shaft rotation, we can provide limits that are adjustable throughout the entire range of movement. Rotary Limit Switches can be used for material handling on crane or winch drums, hoists, lifts, screw jacks, or platforms. They can also be used to limit gate travel on locks, dams, intake water structures, or any moving item.
