The Husqvarna 504739401 Button is a genuine OEM replacement designed for the PG680 and PG820 floor grinders. Sourced directly from Husqvarna, this part meets the same specifications as the original component installed at the factory.

Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional standards, ensuring correct actuation feel, travel, and contact engagement specific to this control button application.
- Direct Drop-In Replacement — Engineered to seat and secure exactly as the original, connecting to existing mounting points without modification to the housing or surrounding components.
- PG680 and PG820 Compatibility — Verified fitment for both the PG680 and PG820 planetary floor grinders, covering a widely used range of Husqvarna surface preparation equipment.
- Restored Operator Control — A functioning button ensures the operator can engage and disengage machine functions cleanly and predictably; a worn or damaged button can compromise control response and interrupt workflow.
The Button serves as a tactile operator control interface on the PG680 and PG820 floor grinders, allowing the operator to activate or switch machine functions from the control panel. Over time, repeated use can cause wear to the contact surface or internal mechanism, resulting in unresponsive or inconsistent input. Replacing a degraded button with a genuine OEM part restores full, dependable control response and keeps the grinder operating as intended.
