Summary

This part is a turn signal switch for Euro Truck Simulator 2/American Truck Simulator to be added to the steering wheel controller. To be recognized as a gamepad, it is connected to the M5Stack ATOMS3.

Required Parts

• 3D printed these parts x2 set
• 3 position Toggle Switch (on-off-on) x2
• Self-Tapping screws (2mm x 8mm) x8
• M5Stack ATOMS3 x1
• M5Stack ATOMIC DIY Proto Kit for ATOM series x1

How to Buid

1. 3D print these parts.
2. Attach the switch to the chassis. Place a nut across the hole and secure with radio pliers.
3. Wiring to the switch.
4. Attach the lever to the knob of the switch. If the hole is small, insert a hot iron rod to melt it. Fix the gap with grue(or melt it).
