2. Krytron - Wikipedia

   en.wikipedia.org/wiki/Krytron

   The krytron is a cold-cathode gas-filled tube intended for use as a very high-speed switch, somewhat similar to the thyratron. It consists of a sealed glass tube with four electrodes. A small triggering pulse on the grid electrode switches the tube on, allowing a large current to flow between the cathode and anode electrodes.

   The current third-generation IGBTs are even better, with speed rivaling power MOSFETs and excellent ruggedness and tolerance of overloads. [21] Extremely high pulse ratings of second- and third-generation devices also make them useful for generating large power pulses in areas including particle and plasma physics , where they are starting to ...

   A current dependent resistor formed of a fine wire in an envelope, useful for regulating current. humidistat A switch that operates automatically on detecting a change in moisture content of the air. HVAC High Voltage Alternating Current; depending on context, this could be hundreds or hundreds of thousands of volts. HVDC converter station

5. Miniature snap-action switch - Wikipedia

   en.wikipedia.org/wiki/Miniature_snap-action_switch

   In 1937 W.B. Schulte, [2] McGall's employer, started the company MICRO SWITCH. The company and the Micro Switch trademark have been owned by Honeywell Sensing and Control since 1950. [3] The name has become a generic trademark for any snap-action switch. Companies other than Honeywell now manufacture miniature snap-action switches.

6. Failure of electronic components - Wikipedia

   en.wikipedia.org/wiki/Failure_of_electronic...

   A sufficiently high voltage causes avalanche breakdown of the Zener junction; that and a large current being passed through the diode causes extreme localised heating, melting the junction and metallisation and forming a silicon-aluminium alloy that shorts the terminals.

7. Darlington transistor - Wikipedia

   en.wikipedia.org/wiki/Darlington_transistor

   A typical Darlington transistor has a current gain of 1000 or more, so that only a small base current is needed to make the pair switch on much higher switched currents. [2] Another advantage involves providing a very high input impedance for the circuit which also translates into an equal decrease in output impedance.
