Honda ignition switches can become fouled and corroded over time, causing them to seize up, short out, or work intermittently. Common Motor Collective offers a round plug connector–style ignition switch for vintage Honda CB175/CL175 Scrambler, CB350/CL350 Scrambler, SL350, CB450/CL450 Scrambler, and CB750 twins and fours. It comes with two keys and is a direct replacement for your broken OEM switch. While you're at it, pick up one of our key switch covers to protect your new switch from the elements.
The keys included with our ignition key switch are closer in shape to the original Honda-style keys than the aftermarket keys shown in the photo. If you have an ignition switch with the square plug connector, like those on the 360-series twins, you can find that switch here.
Clean the terminals of the connection plug on the wiring harness with some rubbing alcohol and fine steel wool.
