Description
A pressure switch has two main functions: protection and control. On the protective side, it limits refrigeration pressure by stopping the flow of refrigerant if pressures exceed a safe operating limit or if pressures drop too low, usually caused by a leak in the system.

Dual pressure switches are to be used in refrigeration and air-conditioning systems. It is used to provide protection against overly low suction pressure or overly high discharge pressure. The controls are also used for beginning and stopping refrigeration compressors and fans on air- cooled condensers.
