When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

Solid state relays (SSR) are electrically operated switches with no moving components that are used to isolate circuits or batteries, detect faults on transmission and distribution lines, and control ...
