ABSTRACT:
Keyboards having flexible plastic domes which snap when depressed to provide tactile feel, at least some of said domes formed from a sheet of plastic and having a bar shaped concave snap initiator formed in said dome, and an actuator comprising at least one cross bar for engaging the snap initiator to initiate dome depression in situations in which the actuator used to depress the dome does not effectively produce snapping of the conventional dome because of the shape of the actuator.
