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.
