Abstract

Improvements in electrical contact units for switches and relays characterized by a contact unit comprising two electrically conductive diaphragms, which are separated by an insulating spacer and the diaphragms can be made to make electrical contact within the opening of the spacer, having one of the diaphragms an annular projection that constitutes the contact zone where the other diaphragm touches when the electrical contact is formed.
