Relays

Shop for your hobby electronic relays with a wide range of stock available to suit your needs. Relays are handy electronic components that are designed to control an electrical circuit using electricity. Relays come in a variety of states including Normally Closed (NC), Normally Open (NO) and Changeover (CO). What this means in practice is that whenever you apply voltage and current you can change the state of the relay to allow electricity to flow through to another part of your circuit.
