Wiring Diagram Relay 85 And 86 Use

The left side is the pin out of the point is sticking out from at the bottom and the the right side is showing a schematic representation of the relay circuitry. 30 and 87 create the switch to your lights. If the coil is not activated 30 will always be connected to 87a.

That is kind of cryptic isn t it.

Wiring diagram relay 85 and 86 use. 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit. Numbers of a relay. This supply also feeds the other side of the momentary switch. This diagram shows an active spdt relay with power applied to pins 85 and 86.

Looking at the diagram we see the pinout of a typical 12v relay. How to wire your light using a relay the relay will have 4 points on it marked 30 87 85 and 86. Terminal 87 to terminal 86 and relay 2 terminal 86. 87 and 87a are the two contacts to which 30 will connect.

Terminal 85 connect to a suitable earthing point on the vehicle chassis. Terminal 86 from relay 1 terminal 86. Pin 30 common and pin 87a normally closed are connected. Wire colours compressor red pin 30 red battery pin 87 yellow compressor pin 86 yellow binary switch pin 85 black chassis ground note pins 30 and 87 are the power switch while pins 85 and 86 are the relay trigger.

85 and 86 are the coil pins while 30 87 and 87a are the contact pins. This circuit diagram of an inactive spdt relay with no power applied to pins 85 and 86 ground and 12 volt positive. Terminal 86 from one side of momentary switch. Terminal 30 from 12v ignition switch ign position.

Note that each pin is numbered.
