  • If you want to switch high-voltage, high-current AC, I would look into using a transistor and a relay. There are many relay breakout projects or you could build your own on a breadboard. Most relays are designed to switch 250V AC at 10A. The transistor is used to allow a micro controller to switch a higher current to close the relay (typically requires 200-300mA).

No public wish lists :(
