SCR is a semiconductor device used to turn the current on and off. The SCR conduct in one direction when triggered, Triac in both directions. To turn it off the current has to be reversed or turned off by other means. They come in small sizes up to hockey puck size for controlling high power equipment. They were popular in equipment built in seventies and eighties.
