- NEMA 3, 3S, 4X and 6P ratings protect against dust, water and corrosion
Compact Roller Lever Limit Switch
This Eaton LS-S11S-LB is a miniature limit switch designed for machinery and machine-shop applications. Its roller lever plunger actuator mounts on the top of the body and provides 1NC/1NO contact operation. The unit carries NEMA 3, 3S, 4X and 6P ratings for environmental protection.
4 A 400 V AC Switching Capacity
The switch handles up to 4 amperes at 400 volts AC, making it suitable for standard industrial control circuits. It has no DC contact rating, so it cannot be used in direct-current applications. The single-pole double-throw contacts open or close cleanly when the lever is actuated.
Miniature Body For Tight Mounting
Measuring 2.53 in high, 1.22 in wide and 1.32 in deep with a 2.06 in actuator length, the switch fits into confined spaces. The non-boot-sealed actuator requires a clean operating environment. Builders needing a sealed actuator or DC-rated contacts must select a different model.

Questions about this item
Will the 2.06 in roller lever reach the cam on my existing machine guard?
The roller lever extends 2.06 inches from the switch body, so measure the cam-to-mounting-surface distance on your guard to confirm engagement.
How can I verify the 1NC/1NO contacts change state correctly after wiring?
Operate the lever by hand and use a multimeter on each contact pair; the normally closed circuit should open and the normally open circuit should close at the same actuation point.
Does the switch include mounting hardware or must I supply my own screws?
The supplier description lists only the switch body and actuator; mounting screws, wiring terminals and any conduit fittings are not included and must be sourced separately.
