Eaton LS-S11S-LA Limit Switch
This Eaton LS-S11S-LA is a miniature roller lever limit switch designed for position sensing in industrial machinery. It features a top-mounted plunger actuator with a 1.68 in lever length and a 1NC/1NO contact form. The switch carries an AC rating of 4A at 400V and meets NEMA 3, 3S, 4X and 6P enclosure ratings.
Suits AC control circuits needing a compact sealed
It suits automation systems requiring a small-form-factor switch with high ingress protection for wet or dusty environments. The 1.22 in by 1.32 in body fits tight mounting spaces. Buyers needing DC switching capability or a DC contact rating should look elsewhere as this model is AC rated only.
The 4A 400V AC contact rating decides fit
This single specification determines whether the switch can handle the control circuit load. Verify the application voltage and current do not exceed 400V AC and 4A respectively. The miniature body height of 2.53 in and roller lever actuation complete the mechanical interface.

Questions about this item
How often should the roller lever actuator be inspected for wear?
Inspect the 1.68 in roller lever regularly; replace it if the lever shows excessive play, cracking or reduced spring return force.
What is the maximum continuous current the contacts can carry without overheating?
The switch is rated for 4 A at 400 V AC; sustained loads at or near this rating will cause the contacts to reach their thermal limit first.
Does the switch generate noticeable heat or noise during all-day operation?
The miniature body (2.53 in high, 1.22 in wide, 1.32 in deep) runs silently; only a slight temperature rise occurs at the rated 4 A load.
