I have to replace the electric
field sensor switch in the shower/galley sump. The old one is an electric
field sensor switch like in the upper left corner in the attached wiring
scheme. I want to replace it with a simple float switch like the one in the upper right picture.
I am pretty helpless when it comes to wiring
stuff. What I don’t understand is this: The old switch has three wires, while all the replacements
I can find have two. I have attached a wiring scheme as it is by today.
Could somebody who knows this stuff point me in the right direction of what goes where?
Thanks in advance!
