Title Gas-Pressurized Electrical Switch With Current-Generated Magnetic Field For Assisting Arc Extinction Abstract Of The Disclosure A gas-pressurized electrical switch includes a casing pro- vided with a transverse wall dividing the interior into two quenching chambers. A longitudinally movable contact member is supported within one of the chambers and includes a nozzle pipe projecting through the transverse wall into the other chamber for entry into an annular stationary contact member which is surrounded by a magnetic-field producing coil having one end connected to one terminal of the switch. A pin member is locat- ed centrally within the stationary contact member and is entered into the nozzle pipe in the contact-closed position, and this pin is surrounded by an annular electrode. When the contacts disengage, an arc is drawn and thereafter one portion of the arc burns between the annular electrode and the pin and is rotated by the magnetic field, and the other portion of the arc burns between the pin and the nozzle pipe of the movable contact mem- ber. Burning of the arc generates heat which causes an increase in gas pressure in the chamber containing the stationary contact member assembly which then acts to start flow of arc extinguish- ing gas through the nozzle pipe which results in arc extinction.
