ABSTRACT:
The invention includes a mechanism for multi-dome switch having first, second, third and fourth collapsible dome structures. An elongated action bar extends across and bridges a pair of collapsible dome structures. The action bar, each have a top surface and a bottom surface. A notch is formed in the top surface closer to one of the dome structures. Engagement nubs extend downwardly from the bottom surface of the action bar near both ends and are positioned to be received in a respective depression formed on the top surface of the collapsible dome. A switch pedal is positioned for pivotal movement between a first and second forward positions, and a first and second backward (rear) positions.
