View complete product information  
The P6P series gauge pressure switch is utilized in challenging aircraft and military high-pressure applications including hydraulic systems, air-refueling systems, parking brake modules and steering valve landing gear.


  • Long cycle life
  • Seals available for most fluids
  • Rugged stainless steel piston design
A45C Series Altitude Switch  
View complete product information  

The A45C is our most sensitive skeletal altitude switch for use with air or inert gas. The altitude switch is used in aircraft cabin pressure systems, nitrogen radar cooling launches and many experimental rockets or balloon applications. In one balloon application, the A45C altitude switch triggers an automatic "cut down" system to release experimental equipment if a balloon sinks below a height that would pose a safety hazard to aircraft flights. At a lower height a parachute will be deployed to ensure that the payload safely reaches the ground


  • Easy to install - no plumbing to hook-up
  • Lightweight -<1.5 oz
V21F Series Flow Switch  
View complete product information  

The V21F series flow switch is a hermetic sealed switch designed for ultimate performance and reliability. In the M1 Abrams tank, the V21F flow switch insures that coolant flow is available to cool the crew compartment.


  • Inline mounting
  • Nonmagnetic operation
  • Pressure and attitude mountin
ETM Series Switch  
Precision Sensors is pleased to introduce a Subminiature D compatible time delay unit.  
The ETM series of electronic delay allows for easy integration of a time delay circuit to existing electromechanical switches using a D-Sub connector. The unit uses a male and female connector to plug into existing installations. The time delay circuit employs a unique concept that requires the electromechanical switch remain open or closed for a set amount of time before triggering the delay contacts. This feature increase productivity by preventing unwanted nuisance trips caused by transient and startup events.


  • Prevents nuisance trips
  • Mates D-Sub products
  • Reduces retrofit efforts
P8B Series Gauge Pressure Switch  
View complete product information  
The P8B's welded stainless steel construction bellows sensor makes this design suitable for flameproof requirements and for high-pressure application. In one application the P8B- pressure switch is installed on the launch chambers in submarines. It is used for nitrogen reservoir pressure control in lightweight torpedo launchers.


  • Flame Proof
  • Negative-rate belleville spring design for longer life, accuracy and stability
  • Welded bellows for excellent repeatability and low actuation values
V10F Series Flow Switch  
View complete product information  

The V10F series flow switch provides a convenient flow monitoring inline installation solution. The V10F flow switch is currently used in the hydraulic pump on the V22F Osprey engine air intake particle separator. And, was part of the EAPS modification kits installed in the V22F Ospreys deployed to Iraq.


  • Inline installation
  • Magnetic operation
  • Hermetically sealed switch
