Andrew Peleikis of Toronto made a video to show us how to install a "Frankenstein" knife switch to control the 12V lights he bought at Ikea.
So for a little home-improvement hacking this time, I installed a sweet knife switch to turn on/off the ikea lights i put up in my kitchen.
You can use a switch that has bare contacts like a knife switch as long as the power that is running through the circuit is SAFE – 12 volts or so – and even then, don't short the contacts with a fork or what have you, because it will still make a big spark and scare the children.
