Solid-state relay - Wikipedia
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay, but solid-state electronics contain no moving parts and have a longer operational lifetime.
Solid State Relay - Basic Electronics Tutorials and Revision
The Solid State Relay, or SSR as it is more commonly known, has no moving parts but instead uses the electrical and optical properties of solid state semiconductors to perform its input to output isolation and switching functions.

2024年2月23日 · A solid state relay or an SSR is an electronic switching device which can be controlled by applying an external voltage to the control terminals. If we consider function, they are very similar to the electromechanical relays we are familiar with.
What is a Solid State Relay? – Working Principle, Types of ...
What is a Solid State Relay? As the name implies, solid state relay (SSR) works on semiconductors. In contrast to an electromechanical relay which uses mechanical contacts to switch on or off a circuit, there are no mechanical contacts inside the solid state relay.
