The Genie 110771-43103GT Limit Switch with Roller NO/NC is a genuine OEM electrical component built for Genie SX and Z series boom lifts. As an original equipment part, it meets the exact design criteria of the machines it serves, ensuring the switch operates correctly within the control circuit. This part is confirmed to fit the SX-150, SX-180, SX-135 XC, Z-135/70, and ZX-135/70 — cross-reference part number 110771-43103GT against your machine's parts manual to verify the correct application before ordering.
Key Features
- Genuine OEM Electrical Conformity — Manufactured to Genie's original specifications, ensuring correct actuation force, contact rating, and switching logic for the NO/NC configuration.
- Roller-Actuated Design — The integrated roller actuator provides consistent mechanical triggering at the contact point, delivering repeatable switching performance in service conditions.
- Dual NO/NC Contact Configuration — Normally open and normally closed contacts in a single unit allow direct installation into the existing circuit without adaptation or rewiring.
- Broad Compatibility Across Large Boom Platforms — Fits Genie SX super-boom telescopic lifts and Z series articulating booms, including the SX-150, SX-180, SX-135 XC, Z-135/70, and ZX-135/70.
- Operational Safety — Limit switches govern machine movement boundaries and function interlocks on aerial lifts. A faulty switch can cause unpredictable motion behavior; replacing it with the correct OEM part restores proper machine response.
A limit switch detects the position of a moving component and signals the machine's control system to permit or interrupt a specific function when that component reaches a defined point. The roller actuator triggers the switch as the target surface contacts it, changing the state of the NO and NC contacts and sending the appropriate signal through the circuit. When a limit switch fails — through contact wear, physical damage, or internal fault — the machine may lose position feedback, causing functions to behave erratically or fail to operate at all; replacing the switch restores accurate position sensing and correct control response.
