PRESSURE CONTROL
Designed with a single stage position-sensitive operating linkage, this is an ideal electronic pressure switch for freezer applications where the control will be located where it can be readily observed, such as on the door. The SPST switch is completely enclosed in a stainless steel housing and uses a snap action mechanism to switch at one pound pressure rise. This means that once weight is applied to the freezer door, the applied force will generate one pound pressure per square inch of freezer door opening. This force will move the single stage linkage and cause pressure change within the switch and cycle it into its CLOSED position. When the applied force is released
