SPST-NC (1 Form B) Solid State Relays (SSR)
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage is applied across its control terminals. Unlike traditional electromagnetic relays, SSRs have no moving parts and rely on semiconductor components like thyristors, triacs, diodes, and transistors to perform switching operations.
