The Husqvarna 542030071 Switch Assembly Dust Proof With Wire is a genuine OEM component designed for the MS355, MS355G, MS510, MS510G, and MS610 tile and masonry saws. As a direct factory replacement, this switch assembly is built to the same specifications as the original, ensuring correct electrical function and a proper fit from the moment it is installed. DHS Equipment supplies this part to help keep your equipment running reliably on the jobsite.
Key Features
- Dust-Proof Electrical Protection — The sealed, dust-proof housing shields internal switch contacts from the fine silica and masonry dust generated during cutting operations, maintaining consistent electrical function in harsh environments.
- Pre-Wired Assembly — Supplied complete with attached wire, this assembly connects directly to the machine's existing harness, allowing for a straightforward swap with no additional wiring work required.
- Genuine Husqvarna OEM Part — Manufactured to Husqvarna's original switch specifications, including correct contact rating and circuit compatibility, for dependable operation across the machine's full duty cycle.
- Broad MS-Series Compatibility — Confirmed fit for the MS355, MS355G, MS510, MS510G, and MS610 masonry saws. Cross-reference part number 542030071 against your parts diagram before ordering to verify your model.
- Restored Operator Control — A failing switch can cause intermittent starts, loss of power, or a complete no-start condition. Replacing this assembly restores full, predictable control of the blade motor.
- Electrical Safety Compliance — Using a genuine OEM switch assembly ensures the machine's start/stop circuit meets Husqvarna's original safety design intent, which is especially important on power tools operating near water used in wet cutting.
The Switch Assembly Dust Proof With Wire is the operator-facing control that completes or interrupts power to the saw's motor. On masonry and tile saws — where water, slurry, and airborne dust are constant byproducts of cutting — a dust-proof rated switch is critical to maintaining safe and reliable machine control. When the switch assembly degrades, operators may experience intermittent motor response, failure to start, or an inability to shut the machine down cleanly. Replacing the assembly with a genuine OEM unit restores the electrical integrity of the control circuit and keeps the saw responding predictably under load.
