Dc 3 Pin Wiring Diagram

Pin 3 is where the switch is either connected to ground or left open.

Dc 3 pin wiring diagram. Pin 2 is where the accessory that the switch is going to turn on is connected. Crimp the ends onto the wires. Chassis and cpu fans may use either 3 pin or 4 pin power connectors. 4 pin connectors are usually used by cpu fans with higher power consumption.

Below is a pictorial representation of the schematic diagram. This translates into the following model in a real life rocker switch. I ordered recently a 12v dc solenoid valve a valve that s electrically controlled the datasheet of the valve is attached however i received the valve without wires and i m not sure about the wiring connection because there are three pins in the valve and i just want two wires out of the valve to connect it to a 12v dc battery. Wire the switch by connecting power to the center terminal s.

You will have one wire connected to a positive 12 volt source and two wires that go to the loads. By connecting it like this you ll get a voltage divider that decreases the voltage of the input signal. The loads attach to the other two terminals. If unconnected the vehicle s lockout mechanism may not operate.

When you plug in the socket pin 1 2 would provide the power to the circuit and battery will be disconnected. Use of a crimping tool is required. This diagram might help you understand better. 4 3 connector wiring diagrams and pin out charts load 1 3 4 1 brown 2 white 4 not used load.

Panel mount receptacles our bulletin 888 dc micro m12 panel mount receptacles are die cast connectors ideal for use in enclosures or for creating custom wiring configurations. 3 pin connectors are usually used for the smaller chassis fans with lower power consumption.

These connectors are available in male and female 3 or 4 pin configurations and in straight and right angle versions. Of course all you need is the red and black wire to run your computer fan but if you didn t know what the extra wires are for this video may help you out. When unplugged the battery would be connected back to the circuit. Brown yellow green blue load l1 l2 l1 l2 1 2 3 1 yellow green.

Insert them into the crimp end of the spade connectors. Here pin 3 will got to the battery pin 2 1 to the circuit. Pin 1 is where the rocker switch receives the input power. Fans may be either 5 volt dc or 12 volt dc fans.
