Abstract: A battery switch has two identical, nested terminals separated by an insulator and having aligned openings for receiving a connecting bolt. The bolt when installed in the openings provides electrical connection between the terminals. Each terminal has a lug for connection to a battery cable or post, an extension portion attached to the lug and a receptacle for receiving the extension portion of the other terminal. The extension is offset from a central plane so the two terminals fit together along the central plane in a low profile configuration. The interfitting extensions and receptacles lock the terminals together.
