A TRIAC is a bidirectional, three-electrode AC switch that allows electrons to flow in either direction. It is the equivalent of two SCRs connected in a reverse-parallel arrangement with gates connected to each other. A TRIAC is triggered into conduction in both directions by a gate signal like that of an SCR.
