Turns out central heating zone valves, can’t handle 6A:
I couldn’t find a datasheet for it prior to this, autopsy reveals that the micro switch is rated at 2A 🤷
Lesson learned, if in doubt use a relay or contactor.

eBay has become a wank platform, I hate it when they allow sellers to spam the same listing like a 100 times, and fuck those listings where you click on the item and the price is higher than advertised. It’s a shit platform for sellers too, I had a guy purchase something from me and he wanted to return it because he changed his mind; despite my no returns policy (unless faulty) eBay ruled a case in his favour; a waste of my time and I had to pay shipping fees.
