Eaton LS-S11S-RRM Limit Switch
The Eaton LS-S11S-RRM is a miniature, rod-actuated limit switch designed for position sensing in industrial machinery. It features a rotary adjustable rod actuator mounted on the side of the body. The switch provides one normally closed and one normally open contact rated for 4A at 400V AC. Its compact body measures 2.53 in high, 1.22 in wide, and 1.32 in deep.
Suits side-mount rotary position sensing
This switch suits applications requiring a side-mounted rotary actuator with adjustable rod length for precise trip-point setting. The NEMA 3, 3S, 4X, and 6P ratings support use in wet, dusty, or corrosive environments. It is not suited for circuits requiring DC contact ratings or for applications needing a boot-sealed actuator for additional shaft protection.
4A 400V AC contact rating decides fit
The single specification that determines suitability is the 4A at 400V AC contact rating. The switch carries no DC rating, so it must only be used in alternating current control circuits within that voltage and current limit. Exceeding 4A or 400V AC will cause contact failure and unsafe operation.

Questions about this item
How do I mount and adjust the 6 in rotary rod on the LS-S11S-RRM, and what step is often missed?
Secure the miniature body using its 1.22 in width and 1.32 in depth mounting points, set the rod length, then verify the 1NC/1NO contact action at the trip point; the missed step is confirming actuation before final tightening.
What maintenance will the side-mounted adjustable rod actuator need over time?
Inspect the rotary rod and pivot for wear or debris, check the 1NC/1NO contacts for pitting, and ensure the NEMA 3, 3S, 4X, 6P seals remain intact; replace the switch if actuation becomes inconsistent.
What limit appears first when the switch runs continuously at its 4A 400V AC rating?
The 4A at 400V AC contact rating is the primary limit; sustained operation at this load will cause contact heating and wear before any other factor, and the switch has no DC rating.
