If the key switch on your C.T.M. scooter needs replacing, then you have found the right page. The combination lights and key switch assembly with keys for the C.T.M. HS-320, HS-360, & HS-580 mobility scooters is a direct C.T.M replacement for the original. A set of two keys is included. There are two sets of two wires each. One set of two wires is for the lights, the other is for the key switch.
When key switches fail, the scooter will fail to turn on even when the battery is fully charged and connected.
