Can I test my safety switch?
Safety switches can be easily tested using the 'test' button. They need to be tested regularly to ensure the mechanism continues to work freely and is not gummed up with dirt or other foreign matter. Simply push the button marked 'T' or 'test'. If the safety switch flicks off and cuts the power to the intended circuits, it is working correctly. Check inside your home to see which lights or appliances have been turned off. The circuits turned off by the safety switch test mean they are protected by it. If it doesn't turn off the power, contact your licensed electrician to check it immediately. After testing, turn the safety switch back on.
