<p>The discharge path lies over an insulating substrate between the two discharge electrodes. An ignition electrode projects into this path and is connected to the first discharge electrode through a resistor. The housing (61, 62) contains an ionisable atmosphere, and the switching components consist of metal components lying flat on the same surface of the base plate (11). The discharge path consists of a narrow strip between broad discharge electrodes and the ignition electrodes are placed at the ends of this strip.</p> |
