US Patent 10002731 Rocker input mechanism

A rocker input mechanism includes an actuator that is operable to pivot against the interior surface of a housing through which an actuation surface of the actuator projects. Pivots or up-stops on the edges of the actuator are biased against the interior surface by dome switches contacting a switching surface of the actuator that is opposite the actuation surface. Thus, the actuator is able to pivot with respect to the interior surface to activate the dome switches when force is exerted on the actuation surface without bending or flexing like typical rocker buttons. As a result, the rocker input mechanism may have a feel to a user similar to non-rocking input mechanisms like single mode buttons.
