Twisted Choppers Custom Motorcycle Ignition Key Switch with Spring Return Start

Upgrade your custom build’s starting ritual with a switch that operates with the same deliberate confidence as a factory ignition. No fumbling with toggles or pushbuttons, turn, hold, and release. Purpose-built for custom choppers, hot rods, and bespoke fabrications where clean operation matters as much as the craftsmanship surrounding it.

  • Marine-grade construction delivers superior corrosion resistance in harsh environments
  • Inner seal between cylinder lock and contact plate prevents moisture intrusion
  • Non-conductive housing eliminates risk of accidental shorts
  • 6 screw terminals for secure, straightforward wiring
