A5W-K is 5V DC, Solid State Relay. A Solid State Relay (SSR) is an electronic switching device that is used to control electrical loads without the need for mechanical contacts like those found in traditional electromagnetic relays. Instead of using moving parts and physical contacts, SSRs utilize solid-state components like semiconductor devices (usually power transistors) to perform the switching action.
