An improved keyboard is provided with a flexible metal cover, normally closed switches, and multiple throw switches. The metal cover is made flexible in the area of each key or switch by the provision of grooves in the metal surrounding each flexible portion. The normally closed and multiple throw switches include pellets which transmit the actuating force on a key or switch through a substrate on which a switch is mounted. The device may be configured in such a way that the pellet will push the normally closed contacts of a switch out of contact, or the pellet or pellets may mechanically link a stacked set of switches in order to provided ganged, multiple throw operation.
