Honeywell LSZ52C Limit Switch Adjustable Roller Lever Arm, 1.5-3.5 in Radius, Front Nylon Roller

Honeywell LSZ52C limit switch operating head: adjustable roller lever arm, 1.5 to 3.5 inch radius, front-facing nylon roller. Honeywell's heavy duty limit switch line is a plant-floor standard, and the lever arm is the part that takes the wear.

Replacement lever arms restore travel switches on conveyors, machine guards, and position-sensing stations without replacing the switch body - the arm loosens, swaps, and re-times in minutes, which is why cribs stock arms separately from switches.

Appears unused, no original box. Four available; price is per arm.

Buying the exact OEM part number keeps fit, rating, and mounting identical to what the machine was designed around.

New surplus, available from King Surplus inventory in Del Rio, Texas.

Spec Basis: verified 2026-09-16 against this record's own photographs, which show an adjustable roller lever arm marked CATALOG LISTING LSZ52C, DATE CODE 0051. No manufacturer name is present on the part, so the Honeywell attribution rests on LSZ52C being Honeywell MICRO SWITCH's own catalog listing; it agrees with record manufacturer (FID 56) and model (FID 57 LSZ52C). Radius, roller, material and arm dimensions are Honeywell published catalog data carried by multiple independent distributors. No electrical rating is stated because this is an actuator arm and carries none.
