Electrical harnesses for household appliances

Electrical harnesses for household appliances

There are several components within the products we use daily, on which we rarely stop to reflect on their importance. One of these components is electrical harnesses.

To the common eye, electrical harnesses are nothing more than a group of wires that run through all our appliances, but they are the backbone of our technologies.

This wiring is responsible for transmitting electricity and other signals to the different components of the device, allowing all its functions to be performed immediately and without inconvenience.

Have you ever wondered what gives life to the appliances in your home? It’s not magic; its electrical signals travel through specialized harnesses from refrigerators to washing machines to dryers. You are ensuring that power is distributed efficiently and safely throughout the system.

What is an electrical harness, and what is its importance?

More concretely, an electrical harness can be defined as a set of circuits (cables, terminals, connectors, tapes, among other components) that transfer a signal from point A to point B.

Due to the responsibility that falls on this group of cables, manufacturers submit their manufacturing processes to strict quality controls because only in this way can the safe and efficient operation of the devices be guaranteed. Can you imagine how dangerous it would be if your instruments were to have defects in their cables? You could even accidentally receive an electric shock.

AMN’s wire harness manufacturing: a guarantee of safety and quality

For cable assemblies to work appropriately, it is essential to create specialized manufacturing processes covering the component from its first steps of community to installing protective materials. At AMN, we are aware of the need for excellent products, and therefore we have developed through our experience foolproof methods in our manufacturing.

  • Cutting and stripping of circuits
  • Cutting, stripping, and crimping terminals to cables.
  • Twisting of cables
  • Ultrasonic splicing
  • Sleeving burning
  • Cable routing
  • Assembly of terminals on connectors
  • Electrical testing
  • Placement of clips, ties, products, and tapes
  • Final Inspection
  • Packing

What are the uses of electrical harnesses?

We have already mentioned that electrical harnesses are responsible for carrying electrical signals. However, they all take different calls to the same places.

One primary type of electrical harness is used to connect individual components within the appliance, such as switches and motors.

A second type is designed to carry power to various parts of the appliance with specific needs, such as heating elements.

Another group of wires is used to connect the appliance to external outlets, which provide the power necessary for the entire circuit to be functional.

A final type of wiring is included, considering the characteristics of the appliance, and contemplating complex or high-tech devices.

Ultimately, the choice of a specific wiring harness will depend on several factors, such as the size and complexity of the appliance.

What are the main parts of an electrical harness?

This critical component is built thanks to its different parts, which fulfill specific functions ranging from establishing connections to ensuring resistance to high temperatures.


Applicators (usually made of copper or aluminum) that serve as connectivity with the system where the harness is implemented.


Connection points of the circuits that have been previously cut and graphed.


Piece of a wire of specific lengths in the graphitized area where terminals are placed at each end.


Tubing covers the circuits to protect them against humidity, heat, dust, and movement, among other external factors.


The element’s function is to protect the harness against shocks and isolate the internal noises of the saddle.


The adhesive material is used to cover the harness in parts where too much heat is concentrated.

In the end, its structure seeks to guarantee the functionality of electrical networks in general. They are responsible for carrying signals safely and efficiently from one point to another to ensure system operability.
