Pressure Switches and Vacuum Switches

Air Logic is a manufacturer of miniature precision snap-acting switches that interface from pressure signals to electrical control circuits and from vacuum signals to electrical systems. The snap-action electrical switch provides a positive and reliable response. The switch operation is based on the actuation of a precision snap-acting switch acting against a diaphragm. The extremely short stroke and small volume permit fast response making it ideal for precise pressure and vacuum sensing.

The switches are single pole, double throw for normally open, normally closed, and common terminals which are available from 0.1 to 25 AMP; 15 AMP is standard. For low current applications, gold contact and solid state switches are available. Maximum pressure 100 PSI or maximum vacuum 29.9" Hg. Adjustment ranges 0.5 to 100 PSI or 1 to 28" Hg. Special actuating and releasing settings are available upon request.

The switches include Miniature Switches, Subminiature Switches, Low Differential Switches and Solid State Switches. Pilot Operated Valves are also available.

  • The Miniature Switch is designed for low pressure or low level vacuum applications.
  • The Subminiature Switch is designed for high pressure or high level vacuum applications.
  • The Low Differential Switch is designed for a low difference between the "ON" and "OFF" actuating and releasing set points.
  • The Solid State Switch is a direct interface with solid state electrical circuits.
  • The Pilot Operated Valves are designed to be normally open or closed. The Pressure Piloted Valve has an adjustable pressure pilot setpoint with a pressure output. The Vacuum Piloted Valve has an adjustable vacuum pilot setpoint with a pressure output.
