Genie Key Switch 66811GT (3-Position Maintained with Keys) – Optimized Product Page Content

🔹 Product Overview
The Genie Key Switch part number 66811GT (also cross-referenced as 66811) is an essential 3-position component for safety and control on a wide range of Genie Vertical Mast Lifts and Scissor Lifts.1 This is a 3-Position, Maintained switch, meaning the key stays in the position it is turned to, providing three distinct control states: OFF, Ground Control, and Platform Control.
Located at the ground control panel, this switch governs the operational source of the machine, ensuring only authorized personnel can select between controlling the lift from the ground or allowing control from the elevated platform. The assembly typically includes the key barrel, the electrical base (often 6-pin), and two standard Genie keys.
