FIELD: electricity.
SUBSTANCE: vacuum area, in which there is a fixed contact, is separated by means of a membrane equipped with a damaged weakening line, which in process of connection may be travelled with a device of a movable piston to a contact element. The movable contact element is connected with a piston cylindrical structure, which may be connected with a gas generator. A cutting edge stretching in process of operation via a weakening point is installed on the lower side of the piston at a small distance in front of the damaged line of membrane weakening.
EFFECT: realisation of quick connection by simple means.
