brake switch-N/O or N/C?
 

Did a search-too much info and I didn't find the simple answer I seek. I just need to know if the pressure switches are normally open or normally closed. TIASmileWavy

Just a guess, normally open. I'd say they're wired in parallel so either may complete the circuit. Also another Porsche POS design in MHO. There's something terribly wrong with these switches, they require way too much pressure to activate. Amazed Porsche wasn't sued over this long ago. Definitely a liability issue.

When new and working properly they require no more pressure than any other brake lights. I changed mine out about 2 years ago and they have worked very well ever since.
