The ignition (gray cap) version is compatible with circuits that are normally closed when the lanyard clip is secured to the switch. Pulling the lanyard removes the clip, opening the circuit and stopping the engine.

The kill switch features a durable coiled lanyard that measures approximately 15" when coiled and 48" when fully extended. Ensure replacement if any wear, cuts, or fraying occur. It has a mounting hole measuring 5/8" in diameter and accommodates a maximum panel thickness of 5/8" with a maximum draw of 5A.
