Abstract (en)
[origin: WO9508832A1] A power switch has a pole unit (1) with a switch contact arrangement (3), an arc quenching device (4) and a flow channel (19). Switching gases from the arc quenching device (4) are taken into the flow channel (19) and, after cooling, taken to the side of the switch contact arrangement (3) away from the arc quenching device (4). The entire gas chamber of the power switch is essentially sealed. The flow channel (19) may comprise a valve flap (27) and a deionising device (24).
