Simagic Alpha Evo Pro On/Off Switch Extension

Simagic Alpha Evo Pro Power Switch Extension

Overview

This is a power switch extension designed for the Simagic Alpha Evo Pro wheelbase. The extension makes the rear-mounted power button easier to access, especially in tighter sim racing setups.

Assembly

The assembly consists of four individual parts: a base attachment, push rod, rocker arm, and retaining pin. The base mounts to the side of the wheelbase and transfers movement through the rocker mechanism directly onto the original power button. The end of the push rod needs to be inserted fully into the slot on the rocker arm.

Compatibility Notes

This design is not compatible with side-mounted wheelbase setups.

About Me

Hey, I’m Leo / @lskr

I started 3D printing in 07/2025, originally so I could print parts for my own sim racing rig. Over time that evolved into designing functional accessories and practical solutions, mainly for sim racing hardware and aluminum extrusion setups, but occasionally also for things I encounter in everyday life.

I’m still continuously learning, so feedback, suggestions and improvements are always appreciated.
