Piko Transformer PowerSwitch Replacement

This model is a replacement switch component designed for classic Piko model railway transformers. It restores functionality to units where the original plastic switch has broken, worn out, or gone missing over time.

The design focuses on dimensional accuracy, durability, and easy printing. It is optimized for FDM printing and requires no supports in standard orientation. The part is compact but strong enough for regular operation when printed with appropriate settings.

Compatibility Notice

This replacement part is designed for specific Piko transformer models. Due to variations between production years and transformer versions, a direct one-to-one fit cannot be guaranteed for every unit.

It is unlikely to be universally compatible with transformers from other manufacturers, and even within Piko models, minor dimensional differences may require slight sanding or small adjustments.

That said, the model provides an excellent starting point for customization. The geometry is simple to modify in CAD software if fine-tuning is needed for your specific transformer.
