Pressure Switches
A pressure switch is an electromechanical device used to monitor and control pressure levels in various industrial and commercial applications. It works by sensing changes in pressure and then triggering an electrical switch to open or close a circuit. Pressure switches can be used to control the operation of pumps, compressors, motors, and other equipment that require specific pressure settings to function correctly. They are commonly found in HVAC systems, hydraulic and pneumatic equipment, water treatment systems, and many other industrial and commercial applications. Pressure switches can be designed to operate in a wide range of pressure values and may include additional features such as adjustable set points, differential pressure sensing, and various electrical connections.
