That one could fit ! But unfortunately it's far too expensive for the project I want to do because I will need around 50 of them.
Just for giving a context, I will build a LEGO-like construction kit recognize by a computer using different value of resistors.
So finally I really don't need to have a jack connector, I just need a 2Pin connection (it could be coaxial, small pin connection like in a arduino, or even magnet or wathever ...).
If some of you have some experience with a cheap 2pin switch connector, it will be awesome !!
Thanks a lot
