The Genie 42730-SGT Toggle Switch SPDT, 2-Position Momentary is a genuine OEM electrical switch built for Genie Z-series articulating boom lifts, including the Z-34 IC, Z-25/8, Z-20/8, and Z-20/8N. As a direct OEM replacement, this switch meets the original design and performance specifications for these machines. Cross-reference part number 42730-SGT against your machine's parts manual to confirm it is the correct switch for your serial number and configuration before ordering.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the original switch configuration, ensuring correct pole type, throw count, and momentary action for the circuit it serves.
- Direct-Fit Replacement — Designed to install in the same position and mounting location as the original, with matching connector and form factor for the listed Genie Z-series models.
- Broad Z-Series Fitment — Confirmed for Genie Z-34 IC, Z-25/8, Z-20/8, and Z-20/8N articulating boom lifts.
- Momentary Action Integrity — The momentary 2-position SPDT function means the circuit is only active while the toggle is held, which is essential for controlled, operator-commanded functions on aerial equipment.
- Operational Safety — A correctly functioning toggle switch ensures operator inputs are transmitted accurately. A faulty or failed switch can cause unresponsive or unintended control behavior, which is a genuine safety concern on aerial boom lifts.
A single-pole double-throw (SPDT) toggle switch routes an electrical signal from one common terminal to one of two output terminals depending on its position. In its momentary configuration, the switch returns to its neutral or default state the instant the operator releases it, rather than latching in place. This behavior is typically used for functions that should only be active while deliberately held — such as movement controls or enabling circuits. When the switch fails, the affected control may stop responding or behave erratically, requiring replacement to restore safe, predictable machine operation.
