Thanks for this post, informations and your work sharing ! Really cool !
If it can help, here is the real parts in the F16 stick :
Stick:
NWS - A/R DISC - Otto P1-10057 21649 9126 - Grey, side button
WPN REL (Pickle Button) - Otto P1-10050 21649 9313 - Red button
Pinky Switch - Otto P1-10057 21649 9126 - Grey, side button
Paddle : - Otto P1-10047 21649 9113 - Lower button
Trigger - Otto Control U2-029 8835 21649
Also, they have an equivalent in MIL ref. such as : MS25089-xx
for inst., MS25089-3AR = will be the red button MSL P1-10050, MS25089-3G = P1-72629 are for the panels, 3C has conical bushing, ..
You can search for MIL-PRF-8805 documentation
But these buttons are quite expensive... I'm looking for a P8-1 C style for the paddle, would someone have a ref. number?
i find this one on Mouser : https://www.mouser.be/ProductDetail/999-P8-111228C , or https://www.mouser.be/ProductDetail/OTTO/P8-111222C?qs=q7YjwOswUuEdXZEtGrIRJg%3D%3D, but not sure what i'll have..
PS : Reveiced an answer from thrustmaster, original buttons are for like 17€ each + expensive shippings fees
