The Genie 66816GT is a genuine OEM N.O. (Normally Open) Contact designed for an exceptionally broad range of Genie and Terex aerial equipment, including TML light towers, GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and AWP, IWP, and DPL personnel lifts. As a genuine OEM part, it meets the exact electrical specifications Genie engineered into these machines, ensuring correct switching behavior in the control circuit where it is installed. Cross-reference part number 66816GT against your machine's parts manual to confirm the correct application before ordering.
Key Features
- Correct Switching Specification — Engineered to Genie's original normally-open contact rating, so the circuit opens and closes at precisely the right threshold for safe machine operation.
- Genuine OEM Construction — Sourced directly from Genie, this contact is manufactured to the same electrical and mechanical tolerances as the unit that left the factory, with no substitution of contact materials or terminal geometry.
- Direct-Fit Replacement — Designed to seat into the original contact block or relay housing without rework, preserving correct terminal alignment and wire connection integrity.
- Broad Equipment Coverage — A single part number covering Genie GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TML and AL light towers, and DPL, AWP, and IWP personnel lifts — verify your model against the fitment list before ordering.
- Electrical Safety Compliance — In aerial lift control systems, a faulty or incorrect contact can cause unintended circuit behavior, including failure to enable or disable machine functions. Using the correct OEM contact keeps the control circuit behaving as designed.
A normally open (N.O.) contact is an electrical switching element that sits in an open — non-conducting — state at rest, and closes the circuit only when its associated switch, relay, or control input is actuated. In aerial work platforms and light towers, N.O. contacts are commonly used in control and safety circuits to signal machine states such as interlock conditions, platform enable functions, or equipment activation signals. When this contact degrades, corrodes, or fails, the circuit it governs may stop responding correctly — causing a function to remain disabled, behave intermittently, or trigger a fault condition. Replacing a worn contact with the correct OEM part restores the intended switching behavior and keeps the machine's electrical system operating as designed.
