This switch is sourced directly from Husqvarna, ensuring it meets the exact electrical specifications of the original part. It is confirmed compatible with the Pro65G and RS8500D floor saw models, and cross-referencing part number 539300112 against your machine's parts diagram is recommended before ordering. DHS Equipment supplies this part to help keep your equipment running at full operational capacity.
Key Features
- Genuine OEM Electrical Specification — Built to Husqvarna's exact resistance and switching tolerances, ensuring correct circuit behavior for both the Nite Lite and water safety functions.
- Direct Drop-In Replacement — Matches the original connector configuration and mounting position, allowing a straightforward swap without reworking wiring or brackets.
- Confirmed Floor Saw Fitment — Engineered for the Pro65G and RS8500D floor saws, covering both model designations used across this saw family.
- Restored Safety System Function — A failed or degraded switch can disable critical water safety and Nite Lite controls; replacing with this OEM part restores those systems to full, intended operation.
- Operational Safety Compliance — As a safety-related switch controlling water flow protection and lighting circuits, using an OEM part with verified switching characteristics is essential for safe, compliant machine operation.
The Switch Nite Lite Water Safety serves a dual control role on Husqvarna floor saws, managing both the Nite Lite illumination circuit and the water safety interlock system. The water safety function is particularly critical — it monitors and controls the water supply used for blade cooling and dust suppression, helping prevent dry cutting conditions that can damage blades and generate hazardous silica dust. When this switch wears out or fails, one or both of these circuits may become unresponsive, compromising both visibility and blade cooling control during operation. Replacing it with this genuine OEM part restores proper switching action and keeps both safety systems functioning as designed.
