The Genie 229977GT is a genuine OEM Normally Open Pressure Switch, 50 PSI, built for Genie GTH series telehandlers. As a direct OEM replacement, this switch is manufactured to the same specifications as the original, ensuring correct operation in the circuit it serves. This part is confirmed to fit the GTH-636, GTH-844, GTH-1056, and GTH-1256 — always cross-reference part number 229977GT against your machine's parts manual to verify it is the correct item for your serial range.
Key Features
- Genuine OEM Electrical Conformity — Manufactured to the original switch specification, including the correct 50 PSI actuation threshold and normally open (NO) configuration for accurate signal output.
- Direct OEM Replacement — Engineered to install in place of the original component without alteration, using the same connector and mounting arrangement.
- Confirmed Fitment — Compatible with the GTH-636, GTH-844, GTH-1056, and GTH-1256 Genie telehandlers; verify against your parts manual before ordering.
- Consistent Switching Performance — A properly functioning pressure switch opens and closes the circuit at the correct threshold; a faulty switch can cause incorrect readings, missed signals, or machine faults that interrupt operation.
- Operational Safety — Pressure switches are control-circuit components that inform machine logic. Replacing a failed switch with the correct OEM part helps ensure the machine responds accurately to pressure conditions in the circuit it monitors.
A normally open pressure switch remains open — allowing no current to flow — until pressure in the circuit reaches its set threshold, in this case 50 PSI, at which point the switch closes and completes the circuit. This signal is used by the machine's control system to monitor or respond to pressure conditions. When a pressure switch fails, it can send a false signal or no signal at all, causing the machine to behave unexpectedly or triggering fault codes that prevent normal operation. Replacing it with the correct OEM part restores accurate pressure monitoring to the circuit it serves.
