Key Features
- OEM Electrical Spec — manufactured to Husqvarna's exact resistance and actuation ratings, ensuring the switch performs within the machine's designed operating parameters rather than approximating them.
- Direct-Fit Installation — engineered to seat and connect exactly as the original, using the same mounting configuration and connector interface for a straightforward swap.
- Broad Floor Grinder Compatibility — fits the HTC510, PG280, PG450, PG510, and PG510I floor grinders, covering multiple models in Husqvarna's planetary grinder lineup.
- Restored Machine Control — a correctly functioning switch delivers reliable on/off and speed control response, keeping the operator in full command of the grinder during surface preparation work.
- Electrical Safety Compliance — using a genuine OEM switch ensures the control circuit operates within Husqvarna's approved electrical tolerances, reducing the risk of unintended actuation or circuit irregularities.
The switch on a floor grinder is the primary operator control point, responsible for powering the machine on and off and, depending on configuration, regulating motor speed or operational mode. When this component wears or fails, the machine may become unresponsive, behave erratically, or fail to start altogether — interrupting surface preparation work and creating a potential safety concern. Replacing a faulty switch with a genuine Husqvarna OEM part restores proper electrical continuity and ensures the control interface functions exactly as intended for the HTC510, PG280, PG450, PG510, and PG510I grinders.
