12 Volt Relay Wiring Diagram

The power source is coming in from the left. Notice the black wire is the only wire that we are controlling through the 2-way switch. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc.

The white wires are wire nutted together so they can continue the circuit. Just use your mouse pointer on this diagram and follow the current flow from black wire hot wire through the 2-way switch, then to the load and return through the white wire neutral. This should give you a good basic understanding how the 2-way switch circuit works and will help you in adding or changing a 2-way switch.

How a 2-way Switch Circuit Looks. So the circuit above when explained should give you a good concept on how this basic circuit works. When wiring a 2-way switch, this image on the left will show how the connections should actually look when all connections are made. Take notice of the ground wire. It's very important that the ground or bare copper wire is connected to the green screw on the switch.

How to read an electrical diagram Lesson #1

All grounds are connected, and the ground is connected at the light when possible. If no connection is available, then attach the ground wire to the box in a solid way. How a 3-Way Switch Works. When wiring a 3-way switch circuit, all we want to do is to control the black wire hot wire to turn on and off the load from 2 different locations.

The diagram here will give you a better understanding how this circuit works and how a 3-way switch is wired. The source power black wire is coming in from the left. It ties into the common on the left switch see image below.

When the left switch is toggled, it connects to the upper circuit and now the circuit is open at the right switch which turns off the light. Toggle the right switch and it connects to the upper circuit and now closes the path and turns the light back on and so on. How a 3-Way Switch Circuit Looks.Switches Switches are pretty straight forward to wire, but problems may arise with multi-pole multi-way switches.

Switch contacts are always drawn in the OFF position.

In the case of rotary switches the wiper arm will always be connected to the first contact which will be the off position. The diagram below shows a 2 pole 4 way switch. The first set of contacts or arc is designated S1a. The contacts are numbered 1 through 4, as switches are always drawn in the off position then the contact connected to the wiper arm will be the OFF position. In the diagram the contacts are labeled 1 through 4 for clarity though with no labeling it is easy to identify the first contact.

Arc b is shown below. It is common practice in schematic drawings to link both switch arcs with a dashed line as shown above. The contact labeled 1 is the switches first position and contact 3 is not used. With all multi pole switches the wiper arm will track, so that if the switch is turned from off two positions then both wiper arms on S1a and S1b would rest on contact 3.

Relays and Contacts As with switches, relays are always drawn in the off are unoperated position. Contacts may be drawn in different ways as shown below; but the middle contact labeled 2 below is the wiper arm and will move when the relay is energized. This contact is called the changeover contactabbreviated CO. The top contact labeled 1 is the normally closed, NC contact relay not energized and contact 3 known as normally open, NO.

When power is applied to the relay coil, the NO contact is then mechanically and electrically contacted to the CO contact. Relay Contact Labeling As shown above, bottom right hand corner the relay has two changeover contacts.

The designation for a relay coil may be, RL or just R. The easiest way to keep track of how many contacts belong to a particular relay coil is to use a denominator with the amount of contacts.

Now for a motor reversing circuit using non latching press button switches. This circuit is quite messy and it is common practice to see the relay coil and its associated contacts separated some distance in the actual schematic.

The majority of icons utilized on a wiring diagram look like abstract versions of the genuine things they stand for.

As an example, a button will be a break in the line with a line at an angle to the wire, similar to a light button you can flip on and also off. A resistor will be represented with a collection of squiggles symbolizing the limitation of current flow. An antenna is a straight line with 3 tiny lines branching off at its end, a lot like an actual antenna.A relay is basically a switch but not like a switch that's on a wall.

A wall switch relies on someone to flip it which will then control a light or some other type load. A relay is switched by electrical power and not a human. This is done by energizing a coil which is internal to the relay and by energizing the coil, the relay changes state just like a wall switch would.

Switch and Relay Wiring

Therefore when you energize a relay, you are switching circuits off and on. Relays have many purposes and are used in a variety of ways such as electronic circuit boards, machines, appliances, automobiles and the list can go on. The main purpose of a relay is to switch electrical circuits off and on at given times and allow circuits to be automated.

A great advantage with relays is the ability to switch many different circuits of different voltage types all at once by using the same relay. Wiring Relays Although relays come in a huge variety of designs, shapes and sizes, They all basically work with the same concept. I'm going to be covering some industrial relay logic and the images you see here are some of the most common types used for industrial controls also called machine controls.

These images show a square 3-pole relay and it's socket on the left and a round 2-pole relay and it's socket on the right. The socket is used to connect your wires to the relay. This particular relay with 3-poles means you have 3 separate switches or what we'll call contacts. And So On. The square relay pinout shows how the relay socket is configured for wiring. This pinout image is only a 2-pole diagram for room on the page purposes, but you can get the picture here with this one since a 3-pole will just have 1 more set of contacts.

As you can see, there is absolutely no difference between the square type and the round type other than the ratings on the relay. Otherwise they work exactly the same. See my Switch Terminology Page for more on contact arrangements if you need to.

By looking at the diagram below we can go through the basic concept of a relay and how they operate. This diagram will show you how simple it is to control motors, lights, valves, other relays and any type load you want. In this example we are simply turning on a light.

Just like basic house wiring, we always want to control switch the hot wire. So as you can see below, L1 goes down into a normally closed switch. This means the current travels through that switch until it see's an open switch and cannot go any further.

Now the 2 MCR contacts which are normally open as shown will now close. This allows current flow through the contacts and energizes the light. Now to turn the light off, you simply depress the STOP button and this will open the circuit to the relay, de-energizing the coil. The relay contacts open to their normal state and stop the current flow to light. There you have it. A relay circuit.

Now these diagrams are known as relay logic or ladder diagrams. It's using relays to control the circuit and also the diagram will begin to take the shape of a ladder as the relay logic grows. It will continue downward as you will see later on.
