Abstract: A pressure switch system provides a safety mechanism for equipment at a well site environment to prevent the opening or release of certain components when an unsafe condition exists. A pressure switch assembly of the system includes a diaphragm that transitions to an extended position as pressure of a pressurized fluid is flowed through a fluid pathway of the assembly. The diaphragm couples to a pin that transitions along with a dart based on the pressure at the diaphragm. When pressure reaches or exceeds a threshold, the dart is transitioned to a location proximate to a sensor. The sensor triggers actuation of a switch to prevent release or opening of a remote connector of a hydraulics unit until the pressure is at or falls below the threshold. The threshold is set to a pressure based on the unsafe condition.
