Key Features
- Genuine OEM Specification — Manufactured to the original electrical and mechanical spec, delivering the correct switching signal the control system requires.
- Direct-Fit Replacement — Engineered to match the original mounting points and connector interface, allowing straightforward installation on compatible machines.
- Broad S and SX Series Coverage — Fits a wide range of Genie telescopic boom lifts including S-100HD, S-120HD, SX-105 XC, SX-125 XC, S-125, S-105, S-3200, and S-3800.
- Operational Reliability — A functioning limit switch correctly signals machine position and movement boundaries; a faulty one can cause erratic behavior or prevent the boom from operating within its intended range.
A limit switch is an electromechanical device that detects the position or movement of a machine component and sends a signal to the control system when a defined boundary is reached. On telescopic boom lifts, operational limit switches help the machine's controls monitor boom position and movement, triggering the appropriate response — such as slowing, stopping, or enabling a function — when a set point is hit. When a limit switch fails or produces an intermittent signal, the machine may behave unpredictably, restrict functions incorrectly, or trigger fault codes, making prompt replacement with the correct OEM part essential for safe and reliable operation.
