Automotive Relays | Bosch Automotive Relays

Chief sources and stocks automotive relays and solenoids in various pin layouts for a variety of 12V and 24V applications. Relays are electrical components that act as switches, using a small input current to open and close a switch, typically controling a high current. In order to operate, relays use a coil of wire, which creates a magnetic field when supplied with current. This field will pull/push an armature with a contact on its end so that it either completes a circuit by touching another contact, or turns a circuit off by separating them. Electrical relays are vital components and Chief offers mini, micro, high current , power, and specialty relays. Relays come in four main forms: SPST (1 Form A), SPDT (1 Form C), DPST (2 Form A), and DPDT (2 Form C). We support legacy Bosch relays, TE Connectivity, and HongFa relays.
