Deutz M620 Ventilation Switch Tractor

This is reverse engineered switch from a Deutz M620 climatic switch with 4 positions. Its the switch you need for the power of the fan, not for the temperature. But it might fit aswell, i havent tested that yet.

You need to print both parts and you need a spring. I took one of a ballpoint pen. Maybe you could use the original spring wich should still be inside the origial switch.

For assembly:
Simply insert the part called "Raste" into the spring, then insert the other site of the spring into the part called "Drehschalter". Assembly is tricky, but doable.

Support is needed, i printed it in PLA, its doing its job.
