Solid state relay videos

A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. Packaged solid-state relays use power semiconductor devices such as thyristors and transistors.

Here are some SSR videos worth to watch:
