摘要 The invention concerns a multi-domed switch. It relates to a multi-domed switch of the push-button type for thin printed circuit possessing a thin substrate (20) against one face of which a printed circuit having connection pads is placed. The switch comprises two domes (12) and an insulating spacer, the peripheral parts of the two domes (12) are each in contact with one face of the spacer and are thus facing each other on either side of the spacer, each dome (12) possesses a connection member (18) for connection to a connection pad of the printed circuit (20), and the spacer has a central hole large enough for the tops of the two domes (12) to be able to come into mutual contact when they are subjected to a closing-off force.
