The Genie 88356-11BJ5GT is a genuine OEM Limit Switch with Roller Arm, NO/NC, built for S-40 and S-45 series telescopic boom lifts. As a direct OEM replacement, this switch meets Genie's original design and electrical specifications, ensuring it integrates correctly with the machine's control circuit without adaptation. It is compatible with the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF — covering the full range of current S-40 and S-45 variants. Cross-reference part number 88356-11BJ5GT against your machine's parts manual before ordering to confirm it is the correct item for your unit's configuration.
Key Features
- Genuine OEM Electrical Specification — Manufactured to Genie's original switching specification, including correct NO/NC contact configuration and roller arm geometry, so the switch operates exactly as the machine's circuit expects.
- Roller Arm Actuation — The integrated roller arm allows consistent, repeatable actuation by a moving machine element, maintaining accurate switching performance over the component's service life.
- Dual NO/NC Contact Output — Normally Open and Normally Closed contacts in a single unit provide flexible integration with the boom's control logic without the need for additional components.
- Full S-40 and S-45 Variant Coverage — Fits the XC, TRAX, and HF variants of both the S-40 and S-45 telescopic boom lifts, making this the correct switch across the current S-series range.
- Control Circuit Integrity — A failed or misaligned limit switch can cause incorrect machine behavior, including functions that fail to enable or that do not stop at the correct position. Replacing a worn switch with the correct OEM part restores proper control response.
- Safety-Critical Function — Limit switches on aerial boom lifts are integral to operational safety, governing position-dependent control functions. Using a genuine OEM part ensures the switch performs to the design intent of the machine's safety-related control system.
A limit switch is an electromechanical device that detects the position of a moving component and signals the machine's control system when that component reaches a defined point. On telescopic boom lifts, limit switches are used to enable or inhibit specific functions depending on the machine's configuration — for example, preventing certain movements outside safe operating positions. The roller arm on this switch contacts a cam or actuating surface as the machine moves, triggering the switch at the correct moment. When a limit switch fails — whether through contact wear, roller damage, or misalignment — the machine may respond incorrectly to operator inputs, including functions that will not activate or that do not stop as intended. Replacing the switch with the correct genuine OEM part restores accurate, consistent switching behavior.
