Abstract
A push-button switch using one dome sheet of plastics with an electrode on one face and a second flat sheet of plastics with an electrode on the face opposite the first one. Between the sheets and below the second one plates of rigid material with holes below the dome are arranged. When the button is depressed the dome snaps over to the other side of the plastic sheet and the electrode contacts the electrode on the flat plastic sheet. By the hole in the plate below the flat sheet a chatter-proof contact is established.
