Solid-State Relay
An SSR (solid-state relay) is a new type of contactless switching component composed of solid-state electronic components. By utilizing the switching characteristics of electronic components, it can make and break the circuit without contact or spark, so it is also called a "contactless switch". It has the functions of amplification and isolation and is very suitable for driving high-power switching actuators. Compared with electromagnetic relays, it has higher reliability, no contact, longer service life, higher speed, and less interference with the outside world, and has been widely used in household appliances and industrial automation products.
