Summary:Embodiments of the disclosure relate to an electric switching unit provided with an arc-blasting unit. In one embodiment, an electric switch can be provided. This electric switch can include an arc-blasting unit with a compression cylinder enclosing a compression chamber mobile together with the mobile contacts, and a stationary piston at an end of the compression chamber, provided with a support rod made up as a blowpipe which channels the gas compressed in the chamber when the contacts separate to a nozzle that directs the flow to a separation place of the contacts so as to efficiently blast electric arcs. The arrangement can be relatively lightweight and can occupy relatively little space.
