Key Features
- OEM Ignition Specification — Manufactured to Husqvarna's exact switching and contact resistance specifications, ensuring consistent electrical performance every time the machine is started or stopped.
- Drop-In Electrical Replacement — Connects directly to the existing wiring harness on the FS6600D and FS6800D, restoring full ignition control without any adaptation or rewiring.
- Confirmed Floor Saw Fitment — Engineered specifically for the FS6600D and FS6800D floor saws, making part verification straightforward for operators and service technicians alike.
- Restored Operator Control — A functioning key switch gives the operator dependable, immediate control over machine power; a worn or failed switch can prevent startup or cause unintended shutdowns mid-cut.
- Electrical Safety Compliance — As the primary operator control for machine power, using a genuine OEM key switch ensures the ignition circuit performs to Husqvarna's original safety design intent.
The key switch is the primary ignition control on a walk-behind floor saw, allowing the operator to power the machine on and off through a keyed contact. It completes or interrupts the electrical circuit to the engine or motor control system, making it essential to both safe startup and controlled shutdown. When the switch wears out or fails, the machine may refuse to start, shut down unexpectedly, or lose the ability to be powered off — all of which can interrupt a concrete cutting operation and create a safety concern on the jobsite.
