Description

technical field [0001] The invention relates to a micro switch in the technical field of micro-electromechanical engineering, in particular to a miniature planar gas spark gap switch. Background technique [0002] The gas spark gap switch based on traditional machining has attracted much attention due to its advantages of reliable operation, strong impact resistance, large pulse current generation, short trigger time and reusability. The traditional gas spark gap switch, whether it is a two-electrode switch or a three-electrode switch, its processing method is developed on the basis of traditional machining technology. In many cases, refractory metal electrodes are welded in a closed cavity. Due to the limitation of processing technology, the volume of the device is often large. At the same time, the welding, fixing and spacing modulation of refractory metal electrodes increase the difficulty of processing and greatly increase the manufacturing cost. [0003] The current ga...
