    Abstract: An accessory may be provided with a button controller having a microphone and switches. Plastic structures for the accessory may be formed by injection molding. Plastic structures may be molded around switch terminals. Switches may be formed using dome switch members and the switch terminals. A printed circuit with components may be mounted in the plastic structures. Recesses in the structures may be configured to receive the dome switch members, components on the printed circuit board, and wires in a cable. A backplate may be used to cover the printed circuit. A layer of plastic may be molded over the backplate to seal an interface created by the backplate. Cable strain relief structures may be molded into the layer of plastic. A lip on the strain relief structures may prevent particles from entering the controller.
