Abstract
A multi-directional switch includes a conductive member with a central contact portion and four side contact portions. A push key can be actuated to press a selected one of four interconnected, conductive, resilient plate portions of an annular peripheral plate or a conductive, resilient plate portion of a central plate against a corresponding one of the central contact portion and the side contact portions. Upon release of the push key, the resilient plate portions of the central plate and the peripheral plate can return the push key to a normal position.
