DEFINITION

Classification: 361/2

Arc suppression at switching point (i.e., includes solid-state switch):

(under subclass 1) Subject matter for preventing or extinguishing arcs at the main switching points of the switching device.

218, High-Voltage Switches With Arc Preventing and Extinguishing Devices,

1+, for switches having arc preventing and extinguishing features.

333, Wave Transmission Lines and Networks, 19, and 20 for differentiating, integrating and wave shaping networks, some of which can be used to prevent a rapid rise of voltage when a switching contact is opened.
