A useful regulator

This afternoon, my brother called me. I received the call and spoke with him. He asked me to come to his house. When I arrived, he gave me something and asked, "What is this?" He explained that it was a regulator and that it had broken. He told me to take it to the shop and get it fixed. So, I took it to the market, showed it to a mechanic, and he fixed it for me.

The regulator is used to control the speed of a fan, either increasing or decreasing it. It is an electrical component. I really liked looking at it, and I found it very beautiful. So, I took several pictures of the regulator, and since I liked them so much, I decided to share them with you.
