Have a need to place an extractor fan within reach of a shower so obviously have to fit a 12V one. No problem there, but I would like it to be humidistat switched, looking around I could only find a limited number of examples.
Has anyone used one of the separate humidistat switches, switching the transformer and does it cause any problems? Or do I have to hunt for a mains powered switch with volt free contacts and switch the 12V side?
