The "shockless" design of this high-quality switch protects the driver from magneto voltage and the motor from no-starts even in very humid conditions. Multiple hard silver contacts are utilized for long life and stick-free operation through over one million cycles. The big red button pushes in and locks to ground the magneto and leave the ignition in a safe condition for engine maintenance. Twisting the knob clockwise pops the actuator out to un-ground the circuit.

This affordable solution leaves hardware store toggle switches in the dust and the ultra-spendy switches looking silly.

This dual pole kill-switch is capable of grounding up to two Mallory or Vertex magnetos. It will also ground the MSD Pro Mag 12 & 20 in single configuration. This switch should not be coupled with the Pro Mag 44 unless used in conjunction with a relay. For that application, you'll want to use this switch.

The screw-in lug design prevents the switch from rotating in the dash panel like the traditional sleeve/nut switches.
