Product Overview
Universal-style 3-wire ignition key switch with two keys for selected ATVs, motorcycles, scooters, go karts, dune buggies, UTVs, mowers, and similar small-engine applications.
The switch uses a 3-wire / 3-terminal configuration and is listed for selected 50cc, 90cc, 110cc, 125cc, 150cc, and 250cc powersports applications.
Because ignition-switch wiring and mounting designs vary between vehicles, fitment should be confirmed by the 3-wire circuit, terminal arrangement, switch functions, mounting dimensions, and original switch design rather than engine displacement alone.
Product Compatibility
| Vehicle Type | Listed Engine Range | Fitment Notes |
|---|---|---|
| ATV / Quad | 50cc–250cc | Selected 3-wire applications |
| Motorcycle | 50cc–250cc | Verify wiring and mounting |
| Scooter | 50cc–250cc | Selected compatible configurations |
| Go Kart | 50cc–250cc | Verify 3-terminal circuit |
| Dune Buggy | 50cc–250cc | Physical and electrical comparison required |
| UTV | Varies | Verify switch configuration |
| Mower | Varies | Verify electrical functions and mounting |
Listed powersports engine sizes include:
50cc / 90cc / 110cc / 125cc / 150cc / 250cc
Fitment Note: Engine displacement alone does not determine ignition-switch compatibility. Vehicles with the same engine size can use different wiring circuits, terminal arrangements, and mounting designs.

Fitment FAQ
Will this part fit my specific model and year?
This is a universal-style 3-wire ignition switch listed for selected ATVs, motorcycles, scooters, go karts, dune buggies, UTVs, and mowers.
No specific make, model, or year is provided. Compatibility depends on the original switch's wiring, terminals, electrical functions, dimensions, and mounting configuration.
Do I need to match the OEM part number?
No OEM part number is provided.
Instead, compare:
3-wire / 3-terminal configuration
Terminal arrangement
Electrical circuit and functions
Key positions
Switch dimensions
Mounting design
Original switch appearance
Physical and electrical compatibility are more important than engine displacement.
What models or situations does this part not fit?
Do not assume this switch fits:
Every 50cc–250cc vehicle
Every Chinese ATV or motorcycle
Every go kart or dune buggy
2-wire, 4-wire, or 5-wire ignition systems
3-wire switches with different circuit functions
Vehicles using incompatible terminals
Applications with different mounting dimensions
Equipment requiring additional START or accessory circuits not provided by this switch
A matching wire count alone does not guarantee compatibility.
What should I check before ordering?
Confirm:
3-wire / 3-terminal configuration
Electrical function of each terminal
Key-switch positions
Terminal type and arrangement
Switch-body dimensions
Mounting dimensions
Original switch appearance
Vehicle wiring diagram where available
Compare the original switch directly with the product photos and specifications before ordering.
