Key Features
- OEM-Correct Electrical Specification — Sourced directly from Husqvarna, this Switch Kit meets the precise switching characteristics and circuit ratings required by HTC and PG series floor grinders — no guesswork on contact ratings or connector type.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and wiring interface, this kit installs into the existing switch housing without alteration.
- Broad HTC and PG Series Compatibility — Fits the HTC280, HTC450, HTC510, PG280, PG400, PG450, PG510, and PG510I floor grinders, covering a wide range of Husqvarna's professional grinding lineup.
- Restored Operator Control — A functioning switch is essential for starting, stopping, and safely managing grinder operation; replacing a worn or failed switch restores full, responsive machine control.
- Electrical Safety Compliance — Using the correct OEM switch ensures the machine's start/stop circuit performs as designed, supporting safe operation and reducing the risk of unexpected startup or shutdown on the grinder floor.
The switch kit controls the power on/off circuit of the floor grinder, giving the operator direct command over machine startup and shutdown. When the switch becomes worn, corroded, or fails entirely, the grinder may refuse to start, cut out unexpectedly during operation, or become difficult to shut down reliably — all of which disrupt workflow and create safety concerns. Installing a fresh, OEM-spec Switch Kit restores clean, positive switching action and returns the machine to safe, predictable operation.
