I try to understand the issue with the single wire non-isolated pressure switch. I'm interested to buy one of these pressure switches for spare but don’t exactly know how to order. I can find in Internet on official VolvoPenta.com, Marinepartseurope.com or other sites the pressure switch, but I’m not sure I will receive a single wire non-isolated pressure switch.
Can you ore someone from the group please enlighten me on this topic?
