摘要： A female interrupting contact for a current-interrupting unit includes a smoothly contoured, apertured pressure ring which is held in a groove formed in the wall of a bore through a contact body. A flat spring in the groove maintains the ring to one side of the bore so that the aperture is normally misaligned with the path of a male contact through the bore. When the male contact enters the aperture, it moves the ring against the action of the flat spring to align the aperture with its path. This alignment effects intimate sliding engagement between the male contact and both the ring and the wall of the bore, one or both the latter of which are conductive so that a reliable electrical path through the contacts and the interrupting unit is established. The male contact moves out of one end of the bore after the electrical path is established and arcing occurs between the contacts. The other end of the bore is closed. Gas evolved by the arc is unable to flow into the bore, due to this closure, and is carried away from the vicinity of the one end of the bore by passages defined by the contact body. Thus, the evolved gas is unable to blow the arc into the bore, which is thereby kept free of asperities which might impede movement of the male contact.
摘要翻译：用于电流中断单元的阴型中断触点包括平滑轮廓的有孔压力环，其通过接触体保持在形成在孔的壁中的凹槽中。凹槽中的平板弹簧将环保持在孔的一侧，使得孔通常与阳接触件穿过孔的路径不对准。当阳接触件进入孔口时，它使弹簧抵靠弹簧的作用移动，以使孔径与其路径对准。该对准实现了阳接触件与孔和壁的壁之间的紧密滑动接合，其中一个或两个导电，从而建立通过触头和中断单元的可靠的电路径。在电气路径建立之后，阳触头从孔的一端移出，触点之间发生电弧。孔的另一端封闭。由于该闭合，由电弧产生的气体不能流入孔中，并且通过由接触体限定的通道从孔的一端附近带走。因此，放出的气体不能将电弧吹入孔中，由此保持没有可能阻碍阳接触件移动的凹凸。

摘要： A gas-pressurized electrical switch includes a casing provided with a transverse wall dividing the interior into two quenching chambers filled with a pressurized arc-quenching gas. A longitudinally movable contact member is supported within a first 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. The nozzle pipe is provided with apertures through the wall thereof in the first chamber which place the two chambers in communication with each other. A pin member is located 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 member. 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 extinguishing gas through the nozzle pipe which results in arc extinction.
