Abstract
An electrical interruption switch for interrupting high currents at high voltages includes a casing, surrounding a contact unit defining a current path through the switch, and a pyrotechnic material, comprising a gas and/or shock wave-generating, activatable material. The contact unit has first and second connection contacts and a separation region. The pyrotechnic material and contact unit are formed such that a current to be interrupted is supplied to the contact unit via the first connection contact and discharged therefrom via the second connection contact, or vice versa. When the pyrotechnic material is ignited, the separation region is exposed to a gas pressure and/or shock wave, such that the separation region is torn open, caved in or separated. At least one chamber in the switch, at least partially delimited by the separation region, is filled with a filling material.
