New provisions for electric gas pressure switches and circuit breakers characterized by the monoblock combination of one set of contacts, one fixed and the other mobile in the form of a nozzle; a container of blowing gas located to the right of the contacts, and which is maintained at the same pressure as a tank with which it is communicated by the series of narrow mouths; a device acting on the position of the movable contact and on the position of a valve whose spring normally closes the dead space to the left of the contacts and so that this valve closes on its own before the action of the valve ends. Device on the position of the contact; and a valve communicated by external control with the ambient air or with said tank, which by a tube controls the pressure of a cylinder where a piston moves whose rod acts on said device.
