Solid-State Relay (SSR)

Schematic symbol

Relay with no moving parts: a small input current lights an internal LED that switches the output through an optical link, keeping the two sides isolated. It switches silently and fast and can often be driven directly from a microcontroller pin. Most SSRs switch only AC or only DC, so check which type you have and its current rating.
