Plated Plastic Electric Contact

Multiple contacts are provided by forming spaced contacts 10 along an edge 12 of an element 14. The element 14 may be a printed circuit board on which contacts 10 are formed.

A molded plastic element 16 is affixed to the element 14, for example, by screws 18. The element 16 has leaf spring elements 20 integrally molded therein with spacing corresponding to the contacts 10.

Each leaf spring 20 has a lug 22 molded thereon. A stepped surface 24 formed on the leaf spring 20 is plated with copper and may be flashed, for example, with gold, to form the second contact of each contact pair.

The pairs of contacts are normally closed due to the bias inherent in the leaf springs 20. Force exerted on lugs 22, as indicated by arrows 26, causes the contact pairs to open.

The element 16 can be fully plated whereby a common connection 28 applies power to all contacts 24.

In the lower figure, an alternate operating structure is shown.
