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

The K&S Technologies 120107 Magnetic Tether Switch is a universal engine kill switch designed for powersports applications including motorcycles, ATVs, snowmobiles, and dirt bikes. Using magnetic actuation technology, this switch provides a reliable and secure method for cutting engine power in an emergency — simply detach the tether and the circuit opens to shut down the engine.

Key Features:

• Magnetic tether actuation — no mechanical lanyard cord to fray, snap, or jam
• Waterproof construction for all-weather and off-road use
• Magnetic coiled tether line stays flexible and secure even in cold conditions
• Normally open configuration — open circuit to run; removing the tether kills the engine
• 7/8 in. handlebar mount — fits standard powersports handlebars
• Universal fitment across a wide range of powersports vehicles

The 120107 handlebar-mount design makes installation straightforward on most standard 7/8 in. bars, and the magnetic switch mechanism offers a durable, low-maintenance alternative to traditional tether cord switches. It is also available in a normally closed configuration (12-0107N) and in a panel mount version (12-0108) for additional installation flexibility.
