Key Features
- OEM Electrical Specification — Manufactured to Husqvarna's exact switching specification, delivering the correct contact rating and actuation response for safe, reliable operation of dust and slurry equipment.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and wiring interface, so this switch installs directly without modification to brackets or harness connectors.
- Broad Equipment Compatibility — Fits the D30, S26, S36, HTCD20, and W70P, covering multiple models across Husqvarna's dust extractor, floor grinder, and wet vacuum lineup.
- Restored Operator Control — A functioning switch gives the operator precise on/off control of the unit; a worn or failed switch can cause intermittent operation, failure to start, or inability to shut the machine down safely.
- Electrical Safety Compliance — Using the correct OEM switch maintains the original circuit protection design, supporting safe operation in dusty and wet jobsite environments where electrical integrity is critical.
The switch is the primary operator control that completes or interrupts the electrical circuit powering the machine. On dust extractors, floor grinders, and wet vacuums, it governs when the motor receives power, giving the operator direct control over the unit's operation. When a switch wears out or fails internally, the machine may become unresponsive to operator input, run continuously without command, or refuse to start — all of which disrupt work and create potential safety concerns. Replacing a faulty switch with a genuine Husqvarna OEM part restores dependable, predictable machine response.
