Abstract

Electrical connectors and contacts for transmitting power are provided. One power contact embodiment includes a first plate that defines a first non-deflecting beam and a first deflectable beam, and a second plate that defines a second non-deflecting beam and a second deflectable beam. The first and second plates are positioned beside one another to form the power contact.
