Description
Overview:
The Stop Switch for Husqvarna T540 XP II Chainsaw is a genuine Husqvarna safety component that interrupts the ignition circuit to shut the engine down instantly. Built with a durable polymer body and robust electrical contacts, it is designed to cope with vibration, dust, and outdoor use typical of professional arborist and grounds work. Engineered for a precise fit on the Husqvarna T540 XP II and T525, it integrates cleanly with the factory wiring for reliable performance. As an OEM part (522 79 82-01), it restores correct stop function when the original switch becomes worn, damaged, or intermittent. This replacement helps maintain control, reduces the risk of run-on, and supports safe handling of compact top-handle chainsaws used at height or in confined spaces.
