ABSTRACT OF THE DISCLOSURE: A high-voltage, blast-actuated power switch is disclosed which includes a sealed switch casing having a pair of electrical switch contacts, at least one of which can be collapsed by the pressure generated by a blasting cap. The switch casing is filled with a high dielectric strength medium having a low compressibility. When a short circuit or overload condition occurs, the blasting cap is ignited thereby generating a pressure wave. The pressure wave is transmitted through the medium and is practically instantaneously applied to the region of contact between the electric switch contacts. The electric switch contacts are deformed by the pressure wave and separate from each other. The switch contacts preferably include predetermined bending or breaking points to facilitate bending or breaking. The switch includes a screen which delays the gaseous materials emitted from the blasting cap from reaching the region between the separated electrical switch contacts. The screen is located between the blasting cap and the region of contact between the electrical switch contacts.
