Abstract

Improvements in pushbutton switches of the type that include a base member, characterized in that the switch comprises a conductive system in the base member on the conductor scheme and an opening in the spacer member, a spring contact plate in the spacer and at the minus one contact nail on the plate, the nail being placed over the opening of the spacer and the plate being electrically conductive and an elastomeric flexible layer on the plate that deflects the flexible layer by deflecting the nail putting it in contact with the conductive scheme.
