A keyboard apparatus includes a group of switches, a key having a corresponding group of plungers, and a chassis structure including a panel and a post. The post projects upward from the panel to support the key for manual movement pivotally into multiple actuated positions in which the plungers actuate the switches. The panel has a group of apertures through which the plungers are movable into actuating engagement with the switches upon such multi-directional movement of the key.
