ABSTRACT:
An electrical switch with pyrotechnic control includes a housing containing a pyrotechnic composition and at least two contacts applicable, for example, to fire an explosive charge in a military application such as a warhead. The switch includes a thin foil having at least one conductive part spaced in the vicinity of the pyrotechnic composition by a spacing washer directly opposite the contacts. Triggering of the composition throws the thin foil in contact with the contacts to complete an electrical connection. The switch is operable with a small amount of the pyrotechnic composition and has a reduced controllable response time.
