When an electromechanical relay switches to an open state from a closed state, the metal contacts can initially oscillate between both states. In combination with an inductive load, the metal contacts can experience an arcing phenomenon, the process in which electrons flow across the gap present between the metal contacts. After many cycles, there is a possibility that the metal contacts weld shut, leading to device failure. This failure mechanism limits the switching cycles of the device, thus limiting overall reliability.
