K&S Technologies 120107N Magnetic Tether Kill Switch Handlebar Mount Normally Closed

The K&S Technologies 120107N is a universal magnetic tether kill switch designed for handlebar mounting. Operating on a normally closed (closed circuit to run) configuration, the engine is cut off when the magnetic tether is removed from the switch body — making it an essential safety device for motorcycles, ATVs, snowmobiles, and other powersports applications.

The switch uses a magnetic coiled tether line that attaches securely to the rider, ensuring reliable detachment when needed. Unlike traditional lanyard-style kill switches, the magnetic connection stays secure even in cold-weather conditions where standard cords can become stiff or brittle.

Key Features:

• Waterproof magnetic switch construction for all-weather durability
• Normally closed circuit configuration — engine runs with tether attached, kills when removed
• Magnetic coiled tether line stays secure even in cold conditions
• Designed for 7/8 in. handlebar mounting
• Universal fitment for motorcycles, ATVs, snowmobiles, and powersports equipment
• OEM-style design matches the look and function of factory kill switches

Also available in a normally open (open circuit to run) configuration and a panel mount version. The 120107N is the handlebar-mount, normally closed variant — ideal for OEM replacement or safety upgrades on a wide range of powersports vehicles.
