A pressure switch is a form of switch that closes an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.


Uses of pneumatic Pressure Switches for Compressors  include:

  • Switch a household well water pump automatically when water is drawn from the pressure tank.
  • Switching off an electrically driven gas compressor when a set pressure is achieved in the reservoir
  • Switching off a gas compressor, whenever there is no feed in the suction stage.
  • in-cell charge control in a battery
  • Switching on/off an alarm light in the cockpit of an aircraft if cabin pressure (based on altitude) is critically low.
  • Air filled hoses that activate switches when vehicles drive over them. Common for counting traffic and at gas stations.
