Kill Button. This kill button operates a compatible engine-stop circuit and must match the motorcycle’s required contact logic, wiring, mounting, and electrical load. Do not assume it is interchangeable with a starter or horn button simply because the housings look similar. Fitment / Compatibility Universal / Custom: Universal/custom engine-stop use only. Confirm grounding or open-circuit logic, momentary or maintained operation, voltage/current requirements, terminals, mounting, and wire routing before ordering. Product Details Use area: Engine-stop / kill switch button. Before Ordering Confirm the motorcycle’s kill-circuit logic with the wiring diagram and continuity-test the button before connection. Mount and insulate the switch securely, then verify reliable engine stop and normal restart operation before riding.
