Key Features
- Genuine OEM Electrical Specification — Manufactured to Husqvarna's exact switching specification, ensuring correct circuit activation, contact resistance, and load rating for the machine's electrical system.
- Drop-In Replacement — Engineered to match the original mounting configuration and wiring connections, allowing straightforward installation on compatible HTC and PG floor grinders.
- Broad Floor Grinder Compatibility — Fits HTC280, HTC450, HTC510, PG280, PG450, PG510, and PG510I floor grinders, covering a wide range of Husqvarna's professional grinding lineup.
- Restored Operator Control — A functioning switch delivers crisp, responsive on/off control of the grinder. A worn or faulty switch can cause intermittent starting, failure to power on, or unintended shutdowns that interrupt surface prep work.
- Electrical Safety Compliance — Using the correct OEM switch maintains the integrity of the machine's electrical circuit, reducing the risk of arcing, overload, or control failure associated with incorrectly rated substitutes.
The switch is the primary operator control that opens and closes the electrical circuit powering the floor grinder's motor. When engaged, it signals the machine to start and run; when released or turned off, it breaks the circuit to bring the grinder to a stop. A switch that is worn, damaged, or internally shorted can cause unreliable starting, unexpected shutoffs mid-pass, or a complete loss of machine control — all of which compromise both productivity and operator safety on the job. Replacing a faulty switch with the correct OEM part restores predictable, dependable machine response.
