Hi everyone,

Does anyone know where I can find a spring loaded three way rotary, with position 3 being spring loaded back to 2. EG:

1-2-3(SPRING)-2

Just like on the Boeing 767 APU rotary switch. I think Opencockpits used to sell them but I can't find them on their shop.

Regards,

Jack;)

Hi, OC's rotary switches have a very long shaft. You could make a lever with the D-hole for the shaft and a spring to push the lever back to position 2. Postion 1 would be away from the spring and not affected.

I will be building these soon along with a solenoid version for B737 starters!
