Triac circuit


Posted on Feb 4, 2014

A lot of my projects involve 120VAC, switching relatively slowly. Most people use mechanical relays in that situation, but I don`t like them; I try to avoid moving parts whenever possible. Up to this point, I`ve always used solid state relays. They work really well, but they`re expensive. What this means is that I`ve needed to move my same 2 SSRs

from project to project, which is kind of a pain. Well no more! Enter the humble Triac. They`re tiny, cheap, and in my slow switching applications the circuitry isn`t too complicated. That being said, it`s still the most complicated circuit I`ve ever attempted. And there you have it. A neat little package with two independently controlled power plugs. The best part is the cost. The whole thing cost less then $10! With SSRs it would have been ~$80, and I don`t know if they even would have fit in the box.
