This switch delivers an exact electrical and mechanical match to the original, ensuring the machine starts, runs, and shuts down exactly as Husqvarna intended. DHS Equipment supplies this part to help keep your floor saw operating at full capability. Cross-reference part number 539300226 against your parts diagram to confirm fitment before ordering.
Key Features
- Genuine OEM Electrical Spec — sourced directly from Husqvarna, this switch matches the original contact configuration, keying pattern, and switching logic of the factory-installed unit.
- Direct Drop-In Replacement — engineered to mount in the original switch position with the same connector interface, so the installation follows the standard service procedure without alteration.
- Confirmed Fitment for PRO65G and RS8500D Floor Saws — validated for these Husqvarna floor saw models; always verify using part number 539300226 and your machine's parts diagram.
- Restored Start and Shutdown Control — a correctly functioning ignition switch gives the operator reliable control over engine start, run, and stop functions; a worn or faulty switch can cause no-start conditions or prevent safe engine shutdown.
- Operator Safety Compliance — the ignition switch is a primary safety-critical control; using a genuine OEM unit ensures the switching circuit meets Husqvarna's original design requirements for safe engine control.
The keyed ignition switch is the primary electrical control that governs the engine's start and stop circuit on a floor saw. When the key is turned, it completes or interrupts the ignition circuit, allowing the engine to crank, run, or shut down on command. A worn or failed switch can result in intermittent starting, an engine that won't stop when the key is turned, or a machine that won't start at all — any of which takes a floor saw out of service and creates a safety concern on the jobsite.
