AccessoriesRelay accessories are products that are used in conjunction with relays to enhance their performance or extend their capabilities. Relays are electrical components that use an electromagnet to control the flow of electrical current in a circuit. They are commonly used to switch circuits on and off, or to isolate one circuit from another. Relay accessories can include a variety of products, such as mounting brackets, sockets, and protective covers, that are designed to improve the installation, operation, and maintenance of relays. Some common types of relay accessories include base plates, terminal blocks, and test jigs.
