I doubt it, i think you will find they are the main battery isolator switches for the engine batteries. I guess you have key switches or light weight switches at/near the helm for turning the batteries on. Those switches will activate the "switches" in your picture. A multimeter at the switches will confirm, you you might be able to check by putting you ear to the switches or putting your hand on them while someone else operates the helm switches.My port engine is failing to turn over and I suspect battery problems. I have no link switch on the helm but discovered these in the engine room. Do folks think that’s what these are for?
Thanks in advance.
FWIW the Owners Instruction Manual is here https://www.thornam-shop.dk/images/pdf/722-NE.pdfThanks Paul for your informative reply.
That’s very helpful, I must have a link switch elsewhere, cannot believe it was built without looking at the build/wiring of the rest of the boat.FWIW the Owners Instruction Manual is here https://www.thornam-shop.dk/images/pdf/722-NE.pdf

Not uncommon for there to be no link switch, my Princess was never fitted with one and both of my engines start from the same set of batteries, so flat batteries equals dead in the water. I fitted a manual link switch as soon as i bought the boat.That’s very helpful, I must have a link switch elsewhere, cannot believe it was built without looking at the build/wiring of the rest of the boat.
Thanks for your time.
Maybe that’s the case then. I have 4 AGM start batteries linked together in pairs to give me 24 volts.Not uncommon for there to be no link switch, my Princess was never fitted with one and both of my engines start from the same set of batteries, so flat batteries equals dead in the water.
