Key Features
- Genuine OEM Electrical Integrity — Manufactured to Genie's original specification, so the switch delivers the correct actuation response and electrical characteristics for the circuit it serves.
- Direct OEM Replacement — Designed to install in the same position as the original, with matching connector and mounting geometry for a clean swap.
- Broad GTH Telehandler Coverage — Fits the GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056, covering a wide span of the Genie telehandler line.
- Maintains Control Circuit Function — A properly functioning auxiliary switch gives the operator reliable command over the functions it controls; a worn or failed switch can cause intermittent response or a complete loss of that function.
- Operational Safety — On aerial and lifting equipment, dependable switch operation is essential to predictable machine behavior. Using a verified OEM part supports the control system's designed intent.
An auxiliary switch provides the operator with direct electrical control over a designated machine function, completing or interrupting a circuit when actuated. On GTH telehandlers, auxiliary switches are used in operator control panels and function-select circuits where reliable on/off or selector response is required. When a switch fails — through worn contacts, a broken actuator, or internal corrosion — the function it controls may become unresponsive or erratic, affecting both productivity and safe machine operation. Replacing a faulty switch with the correct OEM part restores consistent, dependable control.
