Not too long ago, all relays performed their switching duties through electromechanical means. Today, however, engineers can also opt for solid-state relays that use semiconductors (MOSFET) to switch their output circuits. The choice between traditional electromechanical relays and the solid-state varieties often comes down to reliability and performance. With no moving parts, solid-state relays avoid all the obvious mechanical failure modes associated with traditional relays.
