[image] I can get these 10 Amp AC (Phase Control) dimmers (24-380VAC, 50-60 Hz) at a good price. They are controlled by a resistance / pot of 500K ohms of about 1/4 watt rating. They work fine with a typical resistance. NOTE: These terminals are "hot" at the line voltage, not isolated. At 0 output t…
