PST4B Pressure Switch

PST4B Pressure Switch

Pressure Switch Picostat PST4B

Pressure Switch Picostat PST4B 9B4

The PST4B pressure switch is the result of Trafag's decades of experience in the shipbuilding and railway sector. The 9B4 version provides high resistance to vibrations in a compact housing and can be used in a wide temperature range. 

There is also PST4B pressure switch with a plate mounting. 

Proposed applications of the pressure switch PST4B:

  • Shipbuilding 
  • Construction of engines
  • Rail vehicles

Main features: 

  • Increased vibration resistance 
  • Any mounting position 
  • Durable housing
