Description
The Johnson Controls P100AP-340D Pressure Control is a snap-action pressure sensing switch designed to monitor refrigerant or air pressure and respond by opening or closing an electrical circuit when set limits are reached. It operates with factory-calibrated setpoints and is intended for direct mounting on pressure lines or system ports, providing consistent switching under varying operating conditions. The internal mechanism reacts to pressure changes, and reliable circuit action without manual adjustment during operation. Installed in control and refrigeration circuits in HVAC systems, it operates as a pressure sensing control element that supports system monitoring and regulated equipment operation.
