SO ... if your switch is a good quality / low inertia one... it Works !!!

but, of course ... if it works in oil ... ( gear box ...)

magnetic detector looks to be THE thing ... I think telemecanique also have nice proximity switches that can reach 50 or 100 Hz ... ( I have some home ...)

at least it's no more an electronics problem ...
