Abstract

Improvements introduced in manipulation mechanisms with a keyboard, to operate diaphragm switches arranged in a matrix configuration and each equipped with at least one pair of electrical contact elements, one of which is fixed to the diaphragm characterized by an elastically activator deformable having a plurality of deformable projections facing the diaphragm, activator that is located on the opposite side to that which carries the contacts, with the projections aligned with the switches, for their activation.
