The Husqvarna 510016701 Key Switch is a genuine OEM ignition control component designed for the FS6600D and FS6800D floor saws. As a direct Husqvarna OEM part, it is built to the exact electrical specifications required by these machines, ensuring correct start, stop, and safety-shutoff operation from day one. Cross-reference part number 510016701 against your parts diagram to confirm fitment before ordering. DHS Equipment supplies this part to help keep your floor saw operating at full capacity.
Key Features
- OEM Ignition-Grade Specification — Manufactured to Husqvarna's exact switching and contact-resistance ratings, delivering consistent electrical response across the full range of operating conditions these saws encounter.
- Drop-In Electrical Fit — Matches the original connector configuration and mounting profile of the FS6600D and FS6800D, so the switch seats and connects without alteration to existing wiring or the control panel.
- Fits FS6600D and FS6800D Floor Saws — Verified OEM fitment for both machines in the FS6000-series walk-behind flat saw line.
- Reliable Start and Shutoff Control — A correctly functioning key switch gives the operator clean ignition engagement and positive shutoff, which matters on a high-powered slab saw where abrupt or failed shutoff creates a safety hazard.
- Electrical Safety Compliance — As the primary operator-controlled shutoff point, an OEM-spec key switch maintains the circuit integrity the machine's safety system depends on — a worn or faulty switch can prevent emergency shutoff from functioning as intended.
The key switch is the operator's primary interface for starting and stopping the engine on a walk-behind floor saw. It controls the ignition circuit, enabling the engine to crank when turned to the start position and cutting power to the ignition when turned off — which stops the engine and, critically, provides the operator's main means of emergency shutoff. When a key switch wears out or fails internally, the result can be intermittent starting, failure to shut down on command, or a complete no-start condition, all of which take a productive floor saw out of service and can present a safety concern on the cut.
