Quick Block Mains Supply

thingiverse

If like me you are constantly looking for ways to test electrical items quickly without the hassle of searching for the correct mains plug, this is perfect for you.\nI saw these for sale commercially and they ranged from £25 - £50. So I decided to design one myself from scratch and build it within a budget of under £10.\nFirstly, you will need an illuminated power toggle switch, 3 springs and 4 small screws. The screws are probably lying around in your workbench.\n.http://www.maplin.co.uk/p/150-part-spring-assortment-n06cthttp://www.maplin.co.uk/p/everel-16a-rocker-switch-spst-illuminated-red-gu51f\nI organized the build file by color so that you can print all the necessary parts in one go.\nThe Live, Neutral and Earth toggles are distinctively colored, but you could print them all the same color and then paint them (or not).\nYou will need a fused mains cable. I used a 3amp fused plug for mine, then routed the ends through the base block in the cut-outs (Neutral & Earth on one side & live on the other). I soldered these ends to 1mm thick copper strips that I found in an old computer heat sink and they fit perfectly into grooves in the main switch block.\nA small spring under each toggle provides a nice action.\nPlug it in, turn it on at the mains socket and insert each of your wires into corresponding toggles. Always start with the earth wire, then the neutral and finally the live. Then switch on your illuminated toggle switch and voila!
