    • A switch has a gas discharge chamber in which two electrodes, namely a cathode (11) and an anode (12), are arranged at a distance (d) apart and are separated from each other by an electrically insulating wall (9a) of ceramic material or glass. The cathode (1) has a hole (5) and the electrodes (11, 12) are connected to the insulating wall (9a) through a dense metal-ceramic compound or fused material. The gas discharge chamber contains an ionizing low pressure gas under a pressure p such that ignition of a gas discharge occurs between the electrodes (11, 12) at a voltage on the left, descending branch of the Paschen curve. For at least one of the two electrodes (11, 12), the connecting lines (4) at which the respective electrodes (11, 12), the gas and the wall (9a) meet, are located at a minimal distance from the opposite electrode (12, 11) greater than (d), provided that the corresponding electrode (11, 12) is separated from the wall (9a) by a gap (3) whose width is less than (d).
    • 开关具有气体放电室,在该气体放电室中,两个电极(即阴极(11)和阳极(12))隔开间隔(d)布置并且通过陶瓷电绝缘壁(9a)彼此分开 材料或玻璃。 阴极(1)具有孔(5),并且电极(11,12)通过致密的金属陶瓷化合物或熔融材料连接到绝缘壁(9a)。 气体放电室包含处于压力p下的电离低压气体,使得在帕邢曲线的左下降分支处的电压处在电极(11,12)之间发生气体放电点燃。 对于两个电极(11,12)中的至少一个电极,相应的电极(11,12),气体和壁(9a)相遇的连接线(4)位于距离相对的最小距离处 (11,12)与所述壁(9a)隔开宽度小于(d)的间隙(3)的情况下,所述第一电极(12,11)大于(d)。
