What functions and wiring should I expect with this 3-pin ignition?

This is a 3-way rotary push button ignition switch that combines keyed rotary positions with a push-button action for start or power control. The 3-pin configuration is typical for basic ignition, accessory, and starter/power circuits on many small go-karts. If your kart uses more complex wiring or integrated immobilizers, verify wiring diagrams before replacing the original switch.

• 3-pin electrical design for ignition/accessory/starter or power-cut
• Rotary keyed positions for off/on/lock plus push-button start action
• Two keys provided for immediate use and spare
• Simple wiring suited for stock go-kart electrical systems

How easy is installation and what’s included in the package?

Installation is intended to be straightforward for hobbyists and mechanics familiar with small vehicle electrics. The switch installs into the dash or panel with basic tools and connects to the existing 3-wire harness — no special adapters typically required for compatible models. The package contains the ignition switch and two matching keys so you can swap the part quickly and return the kart to service.

• Ships with: 1 x 3-way rotary push button ignition switch and 2 keys
• Fits into existing 3-pin harnesses on compatible models
• Requires common hand tools; no complex programming
• Designed for direct replacement without custom fabrication

Who is this for: Riders, fleet owners, and DIY mechanics who own Hammerhead, Trailmaster, or American Sportworks 150cc–250cc go-karts that need a reliable replacement ignition. It’s best for vehicles using a conventional 3-pin keyed ignition system and for anyone who wants a durable, easy-to-install switch with spare keys included. If your kart has an OEM immobilizer or non-standard wiring, consult your service manual before purchasing.
