2. Krytron - Wikipedia

   en.wikipedia.org/wiki/Krytron

   A sprytron, also known as vacuum krytron or triggered vacuum switch (TVS), is a vacuum, rather than a gas-filled, version. It is designed for use in environments with high levels of ionizing radiation, which might trigger a gas-filled krytron spuriously. It is also more immune to electromagnetic interference than gas-filled tubes.

3. Vacuum interrupter - Wikipedia

   en.wikipedia.org/wiki/Vacuum_interrupter

   After the 1970s, vacuum switches began to replace the minimal-oil switches in medium-voltage switchgear. In the early 1980s, SF6 switches and breakers were also gradually replaced by vacuum technology in medium-voltage application. As of 2018, a vacuum circuit breaker had reached 145 kV and the breaking current had reached 200 kA. [4]

5. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   Industrial pressure switches may have a calibrated scale and pointer to show the set point of the switch. A pressure switch will have a hysteresis, that is, a differential range around its setpoint, known as the switch's deadband, inside which small changes of pressure do not influence the state of the contacts. Some types allow adjustment of ...

7. Thyratron - Wikipedia

   en.wikipedia.org/wiki/Thyratron

   A vacuum tube has the advantage that conductivity may be modulated at any time whereas a thyratron becomes filled with plasma and continues to conduct as long as a voltage exists between the anode and cathode. A pseudospark switch operates in a similar regime of the Paschen curve as a thyratron and is sometimes called a cold cathode thyratron.
