hrnet940 Posted January 20 Share Posted January 20 I have been looking for the proper switch to use in my hornet cockpit as the Bleed Air switch and have not had any luck looking. What are people using or is it out there to be purchased? It need to have four positions and free to rotate without any stops built in.

DeadMeat Posted January 21 Share Posted January 21 Here's expensive example of a switch that is 4 position, 90 degree index and has continuous rotation. You could also go for a cheaper one, open 'er up and cut out the mechanical stop yourself to make it freely rotate. FWIW I think I read somewhere that the real switch is 8 position, even if only 4 of them are connected. Can't find the reference though.

hrnet940 Posted January 21 Author Share Posted January 21 Thanks DeadMeat for the help and suggestion. I bought two of the switch below from Digi-Key. I just finished disassembly, remove the stop and reassemble, after I found the two ball bearings that went flying and have it working. Now comes the truth of hooking it up to my Arduino Uno and checking it out in the cockpit. Wish me luck. https://www.digikey.ca/en/products/detail/c-k/A12405RNCQ/3751952?s=N4IgTCBcDaIMYGsB2BGADATgygtEgJiALoC%2BQA Thanks Again, Wayne Wayne Wilson AKA: hrnet940 Alienware Aurora R3, i7 3820 3.5GHz(4.2GHz setting) processor, EVGA Nvidia RTX 2070 8GB Graphics, 16GB Ram, 1TB SSD.

hrnet940 Posted January 22 Author Share Posted January 22 I hooked up my Bleed Air switch to my Arduino Uno and followed the DCS BIOS for pin hook up. I currently have Right Off to pin 2, NORM to pin 3, Left Off to pin 4 and OFF to pin 5. When I am in the cockpit and turn the switch, it has a mind of its own. It continually wants to sit in Right Off with the occasional stop at something else. When I am moving the switch between settings, it shows that it is continuously rotating when looking at the switch in the cockpit. Why is this happening? I have read everything in the DCS BIOS manual on rotary switch and can't seem to get this rotary switch to work. I think I have everything hooked up correctly.

DeadMeat Posted January 22 Share Posted January 22 Did you connect ground as well? If that's not it, try with different pins or a different switch. Sounds like either a short in the switch you modified or a problem with the UNO My mods --> Mil-spec upgrades for Thrustmaster grips | Real Tornado gear switch modded into gear and hook lever switches Link to post Share on other sites
hrnet940 Posted January 22 Author Share Posted January 22 Thanks for the advice and suggestions. Will try those and see what happens.
