Key Features

• Genuine OEM Electrical Spec — manufactured to Husqvarna's exact resistance and contact ratings for the TS355 series, ensuring the switch performs as the machine's control circuit expects
• DPST Configuration — double-pole single-throw design simultaneously breaks both current-carrying conductors, matching the original wiring harness layout for a direct, tool-free drop-in swap
• TS355 and TS355G Compatibility — engineered specifically for Husqvarna TS355 and TS355G tile and masonry saws, eliminating guesswork on fit
• Restored Operator Control — a worn or failed switch can cause intermittent starts, failure to power up, or an inability to shut the saw down cleanly; replacing it restores full, predictable on/off response
• Electrical Safety Compliance — as a primary power-control component, using a genuine OEM switch ensures the machine meets its original electrical safety rating and prevents unintended energization

The On-Off DPST Switch is the primary power-control component on the TS355 and TS355G tile and masonry saws, responsible for completing and interrupting the electrical circuit that starts and stops the motor. A double-pole single-throw switch opens both legs of the supply simultaneously, providing a clean, safe break in power with a single operator action. When this switch wears out or fails, the saw may refuse to start, cut out unexpectedly during a cut, or — more critically — become difficult to shut off, all of which create hazardous working conditions and interrupt production.
