We manufactured and assembled the contact assembly seen in the image for use in appliance timer controls. AutoCAD software was used to design the automated assembly for terminals, blades and contacts.

The parts were manufactured individually using our stamping process. Brass, used in this assembly, was pre-plated with 100% tin for improved corrosion resistance. The silver contacts were assembled during the stamping process. The customer also saved on inventory as we offered JIT delivery services for the 300,000 pieces ordered. We delivered the contact assemblies directly to the customer’s location in Mexico.
