Mechanical Pressure Switch

Mechanical Pressure Switch – Physical Pressure Control Switch

The mechanical pressure switch is a device that senses pressure changes through mechanical components (such as diaphragms or bellows) and triggers switch actions through physical displacement. It does not rely on electrical signals but uses pressure changes to directly drive the opening or closing of the switch. It is widely used in water pumps, air compressors, hydraulic systems, and other applications that require simple and reliable pressure control.
