11. Using One Mains Switch to Control Two Lamps
    Circuits Analogue Design Vishay BS250
    With just three transistors, one relay, and some resistors and capacitors, a single light switch can provide sophisticated control of high-power and low-power lamps. A brief story behind this idea is as follows: Last month, I created a simple ...
