2. 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 ...

3. Vacuum interrupter - Wikipedia

   en.wikipedia.org/wiki/Vacuum_interrupter

   Vacuum interrupter with ceramic housing. In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers.

4. High-voltage switchgear - Wikipedia

   en.wikipedia.org/wiki/High-voltage_switchgear

   800 kV high-voltage switchgear. High-voltage switchgear is any switchgear used to connect or disconnect a part of a high-voltage power system.This equipment is essential for the protection and safe operation, without interruption, of a high voltage power system, and is important because it is directly linked to the quality of the electricity supply.

5. Switch - Wikipedia

   en.wikipedia.org/wiki/Switch

   A high-voltage disconnect switch used in an electrical substation. Such switches are used mostly to isolate circuits, and usually cannot break load current. High-voltage switches are available for the highest transmission voltages, up to 1 million volts. This switch is gang-operated so that all three phases are interrupted at the same time.

6. Booster pump - Wikipedia

   en.wikipedia.org/wiki/Booster_pump

   A common arrangement for low pressure air powered boosters is for the booster pistons to be direct coupled with the drive piston, on the same centreline. The low pressure cylinder has a considerably larger section area than the high pressure cylinders, in proportion to the pressure ratio between the drive and boosted gas.
