The Genie 139644-14B30GT Tab Blue Micro Limit Switch is a genuine OEM electrical component built for Genie SX-150 and SX-180 telescopic boom lifts. As a direct OEM replacement, this switch is manufactured to the exact specifications of the original part, ensuring correct actuation travel and reliable signal output. Cross-reference part number 139644-14B30GT against your machine's parts manual to confirm this is the correct switch for your unit before ordering.
Key Features
- Genuine OEM Electrical Spec — Manufactured to the original actuation and output specifications, so the switch responds precisely as the machine's control system expects.
- Color-Coded for Correct Identification — The blue tab designation makes it straightforward to match and install the correct switch in multi-switch applications during service or replacement.
- Direct OEM Replacement — Designed to replace the original component on SX-150 and SX-180 super-boom lifts without modification, fitting existing mounting points and wiring connections.
- Confirmed Fitment — Fits Genie SX-150 and SX-180 telescopic boom lifts; verify your serial number against the parts manual to confirm applicability to your specific unit.
- Operational Integrity — A correctly functioning limit switch ensures the machine's control system receives accurate position signals. A failed or misaligned switch can cause incorrect machine behavior or trigger fault conditions that take the unit out of service.
A limit switch is an electromechanical device that detects the position or movement of a machine component and sends a signal to the control system when a set point is reached. On telescopic boom lifts, limit switches are used to monitor boom position, enforce travel boundaries, and enable or disable specific machine functions depending on the configuration of the equipment. When a limit switch fails — through a worn actuator tab, damaged contacts, or electrical fault — the machine may lose position feedback, trigger fault codes, or restrict operation until the switch is replaced with the correct OEM component.
