Eaton LS-S11S-RLA Limit Switch
The Eaton LS-S11S-RLA is a miniature rotary limit switch with a roller lever actuator mounted on the side of the body. It provides one normally closed and one normally open contact rated at 4 amperes for 400 volts AC and carries no DC rating. The compact body measures 2.53 inches high, 1.22 inches wide and 1.32 inches deep, making it suitable for position sensing in tight machine frames.
Build quality and daily use
The switch meets NEMA 3, 3S, 4X and 6P ratings for protection against dust, water ingress and corrosion in harsh environments. Its roller lever extends 2.11 inches from the side, allowing a moving cam or dog to actuate the contacts with a wiping motion that reduces wear. The boot-sealed actuator is not fitted, so the lever pivot remains exposed to the surrounding atmosphere.
What to verify before ordering
Confirm that the application requires only AC switching at 400 volts, as the device has no DC contact rating. Ensure the mounting pattern and the 1.22-inch body width match the available space on your equipment. Verify that the 1NC/1NO contact form suits your control circuit logic and that the NEMA 4X and 6P environmental ratings satisfy the installation conditions.

Questions about this item
What NEMA rating does this 4 A 400 V AC limit switch carry?
It meets NEMA 3, 3S, 4X and 6P ratings, so the enclosure resists rain, sleet, hose-directed water and temporary submersion.
Will the 2.11 in roller lever and 1.22 in wide body fit my existing mounting holes?
The miniature body measures 2.53 in high, 1.22 in wide and 1.32 in deep; check those dimensions against your bracket pattern before ordering.
How do I wire the 1NC/1NO contacts without reversing them?
Identify the normally closed and normally open terminals on the switch block, then connect each circuit to its matching terminal — swapping them reverses the signal logic.
