    Ok here goes... we have a similar problem...

    Our switch goes off, but it won't even let us turn it back on even after I've turned all the switches off. We have to hold it a certain way and turn it on very slowly to allow the power to go back on. I've unplugged things like fridge/computers etc but it still happens, I've also turned off all the power switches and it still won't go back on. Any idea what it could be? We spoke to the RE to come out and have it checked, and the sparky that the RE uses said it sounds like an appliance and probably the fridge and they'd have to charge us to find out what it is. And at $100/half hr I would rather try and be 100% sure its not our fault before him coming out. It just seems weird to me that the switch won't turn back on.

    That is what was happening here, you couldn't put switch back on- it would flick off again straight away.

    But are you saying that if you do it slowly, the power will stay on?

    Yup thats it! Its weird. I hope its nothing major like the fridge as we can't afford a new one right now, but I also don't want an appliance to catch fire either.

    if it just started happening today- it could be that there are power surges in your area due to the heat!
    noticed you are both in melb!!!
    So the problem could be coming from the main exchange rather than your house

    A way to check your fridge Cai is to get a powerboard with safety cut off and put it on the fridge to see if that cuts in or out!

    HTH- just an idea . .. .

    I have been researching for you!

    Is it a safety switch or a circuit breaker that is turning off? (circuit breakers are skinnier than safety switches. safety switch will have a test button on it) They work in different ways. A circut breaker turns off when too much current is passing through it, either due to an electrical fault, or too many items switched on at once eg toaster, kettle, iron, and fridge all at once. A safety switch, otherwise known as an earth leakage device or residual current device (RCD) detect fault in wiring and will shut off before someone gets electricuted.

    If you turn every power point and appliance off in the house (maybe wait til its a bit cooler), and unplug them and then flick the switch normally- what happens?

    If the switch flicks off again (won't stay on), then it is a house problem, so thus the real estate agents problem!

    If the switch will stay on (with all appliances still switched off), then you have to investigate all your appliances on that switch circuit. Start by plugging in, then turning on at wall, then turning on item one at a time, you should eventually find something that will trip it off. If you find something then try a differant appliance in the same powerpoint to determine if it is the appliance or the powerpoint itself.

    hope that helps,
