The Pressure Switch manages pressure-based control by sensing fluid or air pressure within a system and converting that condition into an electrical switching action. When system pressure reaches a defined set point, the switch actuates internal contacts to open or close an electrical circuit, enabling control, indication, or protection functions. As pressure reduces below the set threshold, the switch returns to its original contact state, supporting automatic response to pressure change. This behavior allows the system to react to operating conditions such as pressure build-up, loss, or stabilization without manual intervention.Attributes:• Detects preset pressure thresholds with stable response.• Activates electrical contacts at defined set points.• Operates across repeated pressure cycles reliably.Applications: The Pressure Switch is used in a hydraulic system to monitor pressure conditions and provide electrical switching signals for control, indication, and protection during operation and service activities.
