Pressure Switch

Pressure switches



 
  Pressure switches control on/off of electric condenser fans in response to the pressure in refrigeration cycles. They are also protection switches stop the compressor when the pressure exceeds a predetermined level.

  They are compact, lightweight, and extremely durable.

  The perfect pressure switch for various applications are serialized.Please contact us for specifications

 
 
 
 

 
  A Single Switches
 
  D Dual Switches

Application : High/low pressure protection switch stops the compressor when the pressure in the refrigeration cycle drops below or rises above a predetermined value.
 
  T Triple Switches

Application : Electric fan control and compressor protection switch that integrates a Type A single switch and a Type D dual switch.
