ABSTRACT OF THE DISCLOSURE An electromagnetic waveswitch formed by a rectangular waveguide having a longitudinal axis asso- ciated with a semiconductor wherein the waveguide has dimensions which allow propagation of millimeter waves, the switch comprises: a step centrally formed in the waveguide and defining a ridged space of given volume; a bar of semiconductor material disposed in the ridged space of the waveguide formed by the step; the bar has a high breakdown voltage and a low thermal resistance wherein the volume of the bar is identical to that of the ridged space and wherein the waveguide is formed in a first and a second part with the first part being a flat metal plate and the second part being a U-shaped metal plate in which the step is formed so that the joining together of the first and second parts forms the cavity of the waveguide and the first and second parts are insulated by a layer of insulating material.
