    How Does Touch Switch Surface Area Affect Capacitance?

    Hi, Yes it is connected to the mains but the live wires are not remotely near the metal being touched. I've looked for switches on their own but have had no luck. Searched Maplins and the net but the only things I've found are circuit diagrams. Do you know where I can find these switches...

    How Does Touch Switch Surface Area Affect Capacitance?

    Hi, I've taken apart a touch lamp and remodelled it with my own design. The problem is that now it only works with 50% of the people who use it. The surface area of the switch is much larger than before. Is it a case of replacing a resistor or is there some fundamental problem to having...
