The Genie 66818GT is a genuine OEM NC Contact designed for an exceptionally wide range of Genie aerial lifts and light towers, including TML and AL series light towers, GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and push-around personnel lifts such as the AWP, IWP, DPL, GR, and QS series. As a direct OEM replacement, this contact is manufactured to the same specification as the original, ensuring correct electrical behavior in the control circuits where it is used. Cross-reference part number 66818GT against your Genie parts manual to confirm fitment for your specific machine configuration before ordering.
Key Features
- Correct Switching State from the Start — Manufactured as a normally closed (NC) contact, this part maintains the precise electrical state required by Genie control circuits, eliminating the guesswork that comes with mismatched contact types.
- Genuine OEM Construction — Built to Genie's original design parameters, this contact delivers the contact resistance, current rating, and mechanical engagement the original circuit was engineered around — not an approximation.
- Broad Cross-Platform Compatibility — A single part number that services GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TML and AL light towers, and multiple push-around lift series, making it a practical stocking item for mixed fleets.
- Supports Reliable Control Circuit Operation — A worn or failed NC contact can cause control faults, erratic machine behavior, or a failure to respond to operator inputs. Replacing it with this part restores normal circuit function and predictable machine response.
- Electrical Safety Relevance — In aerial lift control systems, contact integrity is directly tied to safe operation. A normally closed contact that fails open at the wrong moment can disable safety interlocks or trigger unintended responses — making correct replacement critical.
A normally closed (NC) contact is an electrical switching component that completes a circuit in its default, unpowered state and opens that circuit when actuated. In Genie aerial lifts and light towers, NC contacts are commonly used in control relays, safety interlocks, and monitoring circuits where a loss of signal or power must trigger a defined response — such as stopping a function or triggering an alarm. When an NC contact wears, corrodes, or fails, it can cause intermittent control faults, loss of a safety interlock, or a function that runs when it should not. Replacing the contact with the correct Genie 66818GT restores the intended circuit behavior and keeps the machine operating as designed.
