Key Features
- Genuine OEM Electrical Spec — manufactured to Husqvarna's original switching specification, ensuring correct signal output and consistent depth-stop activation every time the circuit is engaged.
- Direct Plug-In Replacement — connects to the existing wiring harness using the original mounting points, so installation follows the standard service procedure without additional hardware.
- Broad Floor Saw Compatibility — fits the FS4800D, FS6600D, FS6600DT, FS6600DJDT, FS6800D, and FS8400D walk-behind floor saws, covering a wide range of Husqvarna FS-series machines.
- Restored Cut Depth Accuracy — a functioning depth stop switch allows the operator to set and repeat precise blade depths in concrete slab cutting, protecting both the substrate and the blade.
- Electrical Safety Compliance — as a genuine OEM electrical component, this switch meets the original design parameters for current rating and insulation, supporting safe, controlled machine operation.
The depth stop switch signals the machine's control system when the blade has reached the operator-set cutting depth, halting further blade travel and allowing consistent, repeatable cuts across a concrete slab. When this switch fails or becomes intermittent, the depth stop function is lost, forcing operators to monitor blade depth manually and risking inconsistent cut depths or unintended over-cutting. Replacing a faulty switch with the correct OEM part restores automatic depth control and the consistent cut quality that walk-behind floor saws are designed to deliver.
