ABSTRACT:
A ball switch for a multi ball-switch arrangement includes a base plate and a metallic circular disk centrally disposed on the base plate. A first electrically-conductive contact track, which is co-planar with the circular disk, extends from the circular disk to a first edge of the base plate. A chamber plate having a through-bore is disposed opposite the base plate so as to form a chamber which concentrically circumscribes the circular disk. The chamber has a metallic inner wall with a circumferential first metallic annular strip disposed at a first end thereof at a first side of the chamber plate. A dielectric sealing ring which concentrically surrounds the circular disk is disposed between the first metallic annular strip and the base plate so as to seal the chamber. An electrically conductive ball is disposed in the chamber and has a diameter which prevents a further similar conductive ball from fitting into the chamber.
