There is no kill switch the planes do not work like that lol
There is no PROVEN kill switch - there have been accusations of it from senior German and Swiss personnel in a position to know (amongst others).
However it doesn't matter, there is a publicly acknowledged issue that works out to pretty much the same - if the US attacks a country with F-35s those planes are functionally worthless very quickly
The ALIS/ODIN system means the US can unilaterally change what is friendly/foe, what is recognised or ignored etc, and if the regular communications for updates aren't maintained the plane goes into the equivalent of your car's "limp home" mode.
TL;DR a hostile US can in advance of an attack (for example) tell your F-35s that all Gripens are hostile, and that X set of "friendly" beacons are now hostile and there's not a damn thing you can do other than not fly the plane. No one other than Israel got an over-ride - because they refused to take the software.

Edit to add "(for example)" as it was unclear that that was just an example of the many things they could do
It would be quite hilarious if it turned out every single operator took that into consideration and secretly deployed countermeasures to nullify that tactic.
Imagine a wing showing up prepared for no resistance and they run straight into it.
It would I imagine look a little like the first 48hours of the Russian attack on Kyiv where the Russians turned up with a brass band in dress uniforms (unarmed unless you count trumpets and drumsticks).
Would love to see it
You build the software?
It's about licenses & you are not allowed to.
A lot of F35 bits the USA air force isn't allowed to even fix bcs licensing & it has to be done by manufacturer.
Bcs monies.
Did you?
"Planes do not work like that". Making a statement like that makes it sound like you would know.
Is it likely there's a remote kill switch? No. But doesn't mean one couldn't exist.
Another commenter accurately pointed out the real problem with using American military hardware is being reliant on the integrated cyber warfare systems exclusively controlled by America
You’re the one claiming without evidence there is a kill switch which is again not how the planes work and also ignores the actual problem we already know about
I'm not the one talking with such certainty. What is known is that they are present in civilian cars. No reason why they wouldn't slip one into a weapons platform. You are so sure it doesn't work that way you better have first hand knowledge or look foolish.
Adding something like that into the software-firmware-hardware would be extremely trivial and easy to hide.
Software yes. Hardware, it's really hard to hide an antenna big enough to pick up such a signal at the necessary range.
Not really, it's already covered in antenna for various other purposes. I can be built into that hardware.
Besides, look at your phone you probably can't see it's antenna. All they need to get in within that range
The antenna on the phone is the case, hence it has plastic gaps around the edge.
Yep exactly. Very easy to hide
