In this video i show you how to wire a 12 volt automotive bosch style relay. Here we look at relay switch pin diagram and the different kinds of relay switches.
Bosch 5 pin relay spotlight wiring diagram bosch 4 pin relay inside 5 pin bosch relay wiring diagram image size 800 x 645 px image source. If you want a normally closed relay you will want to wire to 87a. How is a wiring diagram different from a schematic. This shows the basic internal circuits including any diodes resistors etc and terminal layout to assist wiring.
Relays can look very similar from the outside so they normally have the circuit schematic voltage rating current rating and terminal numbers marked on the body to identify them. Nema and iec markings and schematic. 4 pin relay 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit. If you want a normally open relay you will wire to 87.
A schematic shows the plan and feature for an electric circuit but is not interested in the physical layout of the cords. Here is a picture gallery about 5 pin bosch relay wiring diagram complete with the description of the image please find the image you need. Circuitry layouts demonstrate how the wires are attached and where they must situated in the real gadget along with the physical links in between all the elements. Although most relays are labeled at the bottom you can always find the 30 pin set perpendicular to pins 87 and 87a for easy identification to the power source.
