How does a Dpdt Relay Work? A relay insulated coil automatically flips changeover switches whenever manual switching is impossible. Therefore, it works as a control circuit. Often, relays use devices that look like transistors to carry the electrical loads when applying power. However, we have some type called electromechanical relays. These relays are easy to comprehend. The relays have a low-voltage application to turn the electromagnet into a magnetic field.

double pole double throwDPDT switch stands for a double pole double throw electrical switch. A DPDT switch controls four circuits, allowing two of the four circuits to be energized at the same time.
What is a double throw relay?
This is called a double throw relay * Double throw relays have the ability to control two different circuits with the same relay. * So a double throw relay will let us wire one circuit to the normally open side, and another circuit to the normally closed side.

The SPDT Relay(30A) is a high quality Single Pole Double Throw Relay(SPDT). The Relay consists of a coil, 1 common terminal, 1 normally closed terminal, and one normally open terminal. When the coil of the relay is at rest (not energized), the common terminal and the normally closed terminal have continuity.
What is a double pole double throw contactor?
Double Pole Double Throw relays supply two single double through relays, SPDT, in one relay package. This combination provides tremendous design flexibility. Dual circuit functions can be controlled with a single coil signal.
What is a double pole single throw switch?
A double pole single throw switch controls two circuits (poles) and has 2 states an “on” (closed) state and an “off” (open) state. A double pole single throw has four terminals in total, two inputs and two outputs which are all controlled by the same switch.

What terminal is the 12V battery connected to?
As you can see in the schematic the 12V battery (or use other voltages) is connected with the plus at terminal T1 and minus at terminal T2. The contact 1 and 4 are connected together as 2 and 3 are too.
What happens when a relay is turned on?
When the relay receives 12 volts of power, the relay snaps from the NC position to the NO position. The red LED and the DC fan now shut off and the green LED and the DC motor now turn on and operate.
What happens when a relay isn't powered?
When the relay isn't powered, both the red LED and the DC fan are on,. When the relay is powered, the red LED and the fan shut off and the green LED and the DC motor turn on. This is the circuit below: Since the relay is rated for 12V, it should receive 12 volts in order to power on.
What is COM in relay?
COM - This is the common of the relay. If the relay is powered and the switch is closed, COM and NO have continuity. If the relay isn't powered and the switch is open, COM and NC have continuity. This is the terminal of the relay where you connect the first part of your circuit to.
How many volts should a relay receive?
Since the relay is rated for 12V, it should receive 12 volts in order to power on. It may work with less voltage, but 12V is really what it should receive. This goes into either side of the COIL terminals. Even if you switched the positive and negative voltage of the power supply, it should work exactly the same.
What does "NO" mean on a relay?
NO - This is Normally Open switch. This is the terminal where you connect the device that you want the relay to power, when the relay is powered, meaning when the COIL receives sufficient voltage. The device connected to NO will be off when the relay has no power and will turn on when the relay receives power.
Does polarity matter in a switch?
These are the terminals where you apply voltage to in order to give power to the coils (which then will close the switch). Polarity does not matter. One side gets positive voltage and the other side gets negative voltage. It doesn't matter which order. Polarity only matters if a diode is used.
DC Motor Control using DPDT Switch
The DPDT switch circuit diagram is shown below which is used to control a DC motor. To control a DC motor, first, we need to connect the motor to a switch. Generally, DPDT has six terminals whereas DC motor has two terminals. Here, the switch terminals are represented with A, B, C, D, E, F &G. The connection of this circuit is as follows.
What is a DPDT Switch used for?
The applications of DPDT switch or DPDT switch uses include the following.
What is a DPDT relay?
Double Pole Double Throw (DPDT) Relay contains two coil terminals, two separate common terminals C1, C2 and two Normally Open (N/O1, N/O2), two Normally Close (N/C1, N/C2) terminals, this Relay makes two different connection and control with one control signal to the coil.
What is relay switch?
Relay is a electro-mechanical switch used to control high power application through low power signal electronic circuits, for an example a simple timer circuit working under 5V DC bias can not control high voltage light bulb, by introducing Relay component we can easily control light bulb.
What is the most commonly used relay?
but most frequently used Relays are SPDT Relay and DPDT Relay both are acts as Electromechanical switch.
What does relay mean in a coil?
If there is not enough DC supply in coil terminals then Relay represents idle condition that is common terminal connected in N/C terminal. When the coil gets required DC supply then coil gets Magnetically Energized and this magnetic flux force attracts common terminal lever which is made of iron and makes the connection to N/O terminal, now the N/C becomes open.
What is a DPDT relay?
The DPDT relay is the fourth kind of simple switch. The "DP" means that it is double pole, so it switches both sides of the circuit, and the "DT" means that rather than just turning on and off, it switches from one set of wires to another.
What is a DPST switch?
It positively disconnects all of the power to the building, so it breaks both sides of the circuit. This is a double pole switch, and because it is only on or off, it is a single throw, so it is a DPST switch.
What is a solid state relay?
Many modern relays are "solid state," meaning they use transistor-like devices to do their work. Electromechanical relays, however, are still in use, and the working parts are easy to see and understand. They include an electromagnet, which is turned on by a low-voltage control circuit, and a contact switch, which in turn controls the load circuit. When the electromagnet is energized, it behaves just like someone flipping a light switch, by pulling the switch up or down.
What is an electrical relay?
For example, electrical relays are used to turn on the motor to open an automatic garage door, as well as to turn on a furnace.
How does a wall switch work?
A household wall switch will stay the way you leave it. Turn on the lights, and it stays on; turn it off and it stays off. A relay, however, behaves in a different way. Since it is operated by an electromagnet, when the magnet is de-energized, the switch will go back to its original position. For a DPDT relay, that means that when the control circuit is off, the relay will turn on either circuit A or circuit B. It is the user's choice, but it must be determined before the relay is installed.
