Why do Electrical Prongs have a Hole in them?


After having a closer look at a plug, have you noticed the holes in the electrical prongs? But why do they exist? Or what benefit do they bring? You can get an answer to this question here in this article:

Reasons for the presence of holes in the electrical prongs:

Below are the main reasons for the existence of holes in the electrical prongs:

Better Gripping:

If you come across an open socket, you can observe the bumps in the contact wipers. These are the specific areas where the prongs slide into when you plug any electrical device.

The presence of the holes allows the plug to fix in the socket with great ease and with a firmer grip, ensuring a secure connection.

Ensures safety:

Another benefit of having these holes in the electrical prongs is that the manufacturer can provide detailed instructions on a tag. They can attach this tag inside the hole. 

Such a process ensures that the user cannot plug in any device without removing those tags from the hole. While removing them, a user will surely look at the provided instructions, thus providing a better way to reach a user, especially when it comes to secure device usage.

Savings for the manufacturers:

This reason is a bit too focused on cost-cutting. The presence of holes in the prongs might help the manufacturers save a bit of the raw material while producing the electrical prongs.

Despite reducing metal usage, you cannot consider this practice of creating holes mainly as a cost-saving measure; rather, it is more of a safety technique.
