Pressure Switch

A pressure switch is a device used to monitor and control pressure levels in systems or equipment. It detects changes in pressure and activates or deactivates a switch or relay based on predefined pressure thresholds. Pressure switches are widely used in various applications such as HVAC, industrial automation, hydraulic systems, and pneumatic equipment. They provide reliable pressure monitoring, ensuring safe and efficient operation by triggering alarms, activating pumps or valves, or controlling system pressure.
