relay 12v 87/87b (75.613.116)
| Description | This 12V relay with switching schema 87/87b is a changeover relay that provides both a normally open and a normally closed contact, making it suitable for a wide range of switching circuits in automotive and trailer applications. In its de-energised state, the relay connects to contact 87b; upon energisation, it switches to contact 87. This changeover functionality is essential in applications where two separate circuits need to be controlled by a single relay, such as in lighting systems, motor control circuits, security installations, and auxiliary switching functions on 12V vehicles. The relay housing conforms to standard automotive relay dimensions and is compatible with ISO-standard relay bases and plug-in connectors. It is widely used in professional vehicle fitting, bodywork construction, and electrical system integration where a reliable changeover function is required across 12V DC circuits. |
