Key Features
- Genuine OEM Electrical Specification — Built to the original switch specification, ensuring correct pole configuration, actuation type, and terminal layout for a proper electrical connection.
- Direct OEM Replacement — Designed to replace the original assembly without modification, restoring switch function as it was from the factory.
- Broad Boom Lift Fitment — Compatible with a wide range of Genie S, SX, Z, and ZX series boom lifts, as well as select GTH telehandlers — cross-reference 128203GT against your parts manual for your specific model.
- Momentary SPDT Action — The single-pole double-throw, 2-pole momentary configuration ensures the switch returns to its neutral position when released, which is critical for precise operator control inputs.
- Operator Control Integrity — A failed or intermittent toggle switch can result in loss of function at the control panel. Replacing a worn switch with the correct OEM assembly restores reliable, predictable response at the operator station.
- Safety-Relevant Component — Control switches on aerial boom lifts are directly tied to safe machine operation. Using the correct OEM switch assembly helps ensure the control circuit performs as designed.
A toggle switch assembly on a boom lift is part of the operator control system, allowing the user to send momentary electrical signals that command machine functions from the platform or ground controls. The SPDT 2-pole momentary design means the switch activates a circuit only while held and returns to its off state when released — a common requirement for functions that should not remain energized unattended. When this switch becomes worn, corroded, or fails to make proper contact, the associated machine function may become unresponsive or intermittent, which can interrupt work and affect safe operation. Replacing it with the correct OEM assembly restores the original control behavior.
