Abstract (en)
[origin: EP0758791A2] The keyboard is formed with a frame Ä6Ü that has a pattern of guide bushes Ä6Ü that each receive a pushbutton key Ä7Ü. The metal base Ä2Ü of the keyboard Ä4Ü has a switching foil Ä3Ü that consists of two contact foils separated by a gap. Located on top of this is an actuator foil mat Ä5Ü with a stabilising plate Ä15Ü and is formed with dome elements Ä10Ü having centre projections Ä11Ü. When a key is pressed the dome deflects to bring the projection into contact with the switching foil. The actuator foil is made in an elastomer material.
