Immersion switch is stuck

    So I switched the immersion switch on this morning and now it won’t switch off. It’s stuck. When I try to push switch back to off it won’t move. So for the moment, I’ve switched from bath to sink and have no choice but to leave it on. So first question is - is there any danger? Second question is - what’s the cost of leaving it on 24/7?

    Turn it off at the fuse board. Then replace the switch or get an electrician.

    It’s got a thermostat, so it’s not gonna blow up, despite the legend.

    You don’t by any chance have an immersion timer separate to the switch?

    The water can be heated by gas or electric but I don’t think I have an immersion timer separate to the switch. Here’s some photos

    That's a motorized valve and no use to you in your situation, isolate at the fuseboard as posted earlier and get a new switch fitted by an electrician.

    Is this not more of a DIY project, given that you'll be swapping like for like? Seems excessive to be getting an electrician?

    The switch is melted where the connections are, cable ends and switch will be melted, trip the mcb and get another one.

    Point taken but safety is 1st priority and any loose connections etc and with the heavy loads involved the risk is there and I'm coming from the trade and have seen the damage badly connected switches etc. cause....

    It would be a good idea for an electrician to investigate why the switch got stuck rather than just swapping it for a new switch and having the same thing or worse happen if there is a fault somewhere else in the circuit.

    Unlikely though

    I can't think of anything that wouldn't trip an RCD/MCB

    Most likely problem after would be loose connections or burnt cabling reconnected, or switch wired wrongly

    I agree that it's unlikely and it's more likely to be a mechanical issue with the switch mechanism but if the connections aren't loose and there is damage to the switch it would be a good idea to check the rest of the circuit.
