Relays — Description

A relay switches a high-current circuit using a small control signal, which is why it shows up throughout a car's wiring — cooling fans, extra lights, alarms and more. When choosing one, check the contact current rating, voltage (12V or 24V) and pin count, usually 4-pin or 5-pin. 4shop.lv stocks both standard automotive relays and compact micro relays for tight engine-bay spaces.
