Specialized - Switching Tube ·RelayControlSwitch
Cold-cathode specialized relay and control switching tube. Available source material confirms the control-switch role but does not support a more specific functional description.
This gaseous discharge tube is designed for use as an electronic relay to control large peak currents at high voltages. It is particularly suited for aircraft and indus- trial applications where ruggedness, small size, and long service life are important, and where heater power is not available or warm-up time is not permitted. The tube has a metal envelope and a ceramic base filled with an insulating compound to permit operation at high altitudes with no arc-over. It requires a four-pin socket and can be mounted in any position. Applications for this tube can be found in ignition sys- tems, capacitor discharge welding circuits, pulsing circuits, and control circuits.
