More Information
Summary:A key mechanism including one or more butterfly hinges. Each butterfly hinge may include a double wing design operative to move between a depressed position and non-depressed position. Hinged coupling mechanisms couple respective arms of the wings together. Additionally or alternatively, a key mechanism can include one or more half-butterfly hinges. Each half-butterfly hinge includes a double wing design operative to move between a depressed position and non-depressed position. A hinged coupling mechanism couples one set of corresponding arms of the wings together, while the other set of corresponding arms are not coupled together.
