WebJul 8, 2010 · Thyristors (triacs and their unidirectional cousins, SCRs) are solid-state devices, whereas relays are electromechanical devices. Triacs can switch both AC and DC, but as XTL said, they will not stop the current flow unless the current between MT1 and MT2 falls below a threshold level, or you forcibly commutate the device off. WebTRIAC (Triode for AC) is a semiconductor device widely used in power control and switching applications. It finds applications in switching, phase control, chopper designs, brilliance control in lamps, speed control in fans, motors, etc. The power control system is designed to control the distribution level of AC or DC.
