The RSI Billet Aluminum Momentary Engine Kill Switch is designed specifically for Polaris MATRYX Trail 600, 650, 850, 9R, and Boost models. Precision CNC machined from billet aluminum with a durable black anodized finish, this spring-loaded momentary switch requires a simple push-and-hold to shut off the engine, preventing accidental shutdown while riding. It includes OEM terminal pins pre-crimped to the wiring for installation into your factory connector housing. No wire cutting or splicing is required, although the factory connector must be depinned and repinned during installation. Proudly made in the USA.
