Solange Émile A relay is an electrically operated switch that uses an electromagnet to control a separate circuit. A 12-volt relay is a relay that is designed to operate on a 12-volt power supply. A relay 12 volt wiring diagram is a diagram that shows how to connect a 12-volt relay to a power supply and to the circuit that it will control.
Relays are used in a wide variety of applications, including:
- Controlling high-power circuits with low-power signals
- Isolating circuits from each other
- Protecting circuits from overloads
- Creating timed delays

Components
In a relay 12 volt wiring diagram, the power supply, relay, and load are crucial components that work together to control the flow of electricity in a circuit. The power supply provides the voltage to operate the relay, which in turn controls the load. The load is the device or circuit that is being controlled.
The connection between these components is essential for the proper functioning of the relay circuit. If any of the components are not connected properly, the relay will not operate correctly. For example, if the power supply is not connected properly, the relay will not receive the voltage it needs to operate. If the relay is not connected properly to the load, the load will not be controlled by the relay.
Understanding the connection between the power supply, relay, and load is important for anyone who is working with relay circuits. This understanding will help to ensure that the relay circuit is wired correctly and is functioning properly.
Here is a real-life example of the importance of understanding the connection between the power supply, relay, and load:
A technician is troubleshooting a relay circuit that is not working properly. The technician checks the power supply and finds that it is providing the correct voltage. The technician then checks the relay and finds that it is operating correctly. Finally, the technician checks the load and finds that it is not connected properly. The technician corrects the connection and the relay circuit starts working properly.
This example shows how important it is to understand the connection between the power supply, relay, and load in order to troubleshoot and repair relay circuits.
Connections
In a relay 12 volt wiring diagram, the connections between the power supply, relay, and load are crucial for the proper functioning of the circuit. The power supply provides the voltage to operate the relay, which in turn controls the load. If any of these connections are not made properly, the relay will not operate correctly.

Power supply to relay connection
The connection between the power supply and the relay is typically made using two wires: a positive wire and a negative wire. The positive wire is connected to the positive terminal of the power supply and to the coil of the relay. The negative wire is connected to the negative terminal of the power supply and to the common terminal of the relay. -
Relay to load connection
The connection between the relay and the load is typically made using two wires: a normally open (NO) wire and a normally closed (NC) wire. The NO wire is connected to the NO terminal of the relay and to one terminal of the load. The NC wire is connected to the NC terminal of the relay and to the other terminal of the load.
When the relay is energized, the coil of the relay becomes electromagnetic and pulls the armature towards it. This closes the NO contacts and opens the NC contacts. This allows current to flow through the load.
When the relay is de-energized, the coil of the relay loses its magnetism and the armature returns to its original position. This opens the NO contacts and closes the NC contacts. This stops the flow of current through the load.
Understanding the connections between the power supply, relay, and load is important for anyone who is working with relay circuits. This understanding will help to ensure that the relay circuit is wired correctly and is functioning properly.
Operation
In a relay 12 volt wiring diagram, the operation of the relay is crucial for understanding how the circuit functions. When the relay is energized, the coil of the relay becomes electromagnetic and pulls the armature towards it. This closes the normally open (NO) contacts and opens the normally closed (NC) contacts. This allows current to flow through the load.
The operation of the relay is dependent on the wiring of the circuit. If the relay is not wired correctly, it will not operate properly. For example, if the coil of the relay is not connected to the power supply, the relay will not be able to become electromagnetic and close the NO contacts.
Understanding the operation of the relay is important for anyone who is working with relay circuits. This understanding will help to ensure that the relay circuit is wired correctly and is functioning properly.
Real-life example
A technician is troubleshooting a relay circuit that is not working properly. The technician checks the power supply and finds that it is providing the correct voltage.

Types
In a relay 12 volt wiring diagram, the type of relay used will determine how the circuit functions. There are three main types of relays: normally open (NO), normally closed (NC), and latching.
Normally open (NO) relays are the most common type of relay. When the relay is not energized, the NO contacts are open and the NC contacts are closed. When the relay is energized, the NO contacts close and the NC contacts open.
Normally closed (NC) relays are the opposite of NO relays. When the relay is not energized, the NC contacts are closed and the NO contacts are open. When the relay is energized, the NC contacts open and the NO contacts close.
Latching relays are a special type of relay that can maintain their state even after the power is removed. Latching relays are energized to change state, and then they can be de-energized to maintain that state. Latching relays are often used in applications where it is important to maintain the state of the relay even if the power is interrupted.
The type of relay used in a 12 volt wiring diagram will depend on the specific application. For example, NO relays are often used in applications where the load should be off when the relay is not energized. NC relays are often used in applications where the load should be on when the relay is not energized. Latching relays are often used in applications where it is important to maintain the state of the relay even if the power is interrupted.
Real-life example A technician is designing a relay circuit to control a water pump. The technician wants the water pump to be off when the relay is not energized. The technician chooses to use a NO relay.
