Brass Contact Assembly to be used within an automotive pressure switch

A customer in the automotive industry came to Norstan, Inc. requiring a product which required the stamping of a brass contact assembly, to be used within a pressure switch. We worked closely with the client throughout the process, ensuring all specifications of the supplied 2D CAD drawings were met.

The manufacturing process included die metal stamping and cold heading the rivet in-house. The product was assembled by staking the rivet to the terminal. The state-of-the-art equipment we used included a 45 ton punch press, and a cold heading toggle.

The finished product weighed .005 lbs. The terminal was made of brass-CDA260, and the rivet was made of 75% silver, 24.5% copper, .5% nickel, and was gold plated. It was .70" long, .50" wide, and .032" high. We worked within a tolerance of .002". Upon completion, our team performed full dimensional and contact torque testing.

We promptly delivered the completed contact assembly to the client, who was highly satisfied with our work. To learn more about this project, or for more information on our other products and services, please contact Norstan.
