Pressure switch

As a professional pressure switch manufacturer, we provide reliable pressure switches for industrial pressure control and equipment protection. Our products offer fast response, precise pressure settings, and stable switching performance, with excellent vibration and interference resistance. We support custom pressure switch solutions with various pressure ranges, connection types, and electrical outputs for hydraulic systems, pneumatic equipment, and industrial automation applications.

What Is a Pressure Switch?

A pressure switch is a control device that monitors pressure and opens or closes electrical contacts when a preset pressure threshold is reached. It typically consists of a pressure-sensing element and a switching mechanism. Pressure switches are widely used in industrial machinery, HVAC systems, water pumps, hydraulic and pneumatic equipment to maintain proper pressure and protect equipment.

What Does a Pressure Switch Do?

The main function of a pressure switch is to detect pressure changes and trigger an electrical response when the pressure reaches a set point. It can automatically start or stop pumps, activate alarms, or control other equipment, helping maintain stable pressure, improve operational efficiency, and ensure safe system operation.

We also support testing, validation, branding, and packaging to ensure seamless integration and reliable performance across different industrial applications.

How Does a Pressure Switch Work?

A pressure switch is a mechanical control device that responds directly to changes in fluid or gas pressure without requiring electrical signal conversion. When system pressure reaches a preset switching point, a sensing element such as a diaphragm, piston, or bellows moves and activates the internal switch contacts. When pressure drops to the reset point, the contacts return to their original state. This simple and fast-response design makes industrial pressure switches ideal for pump control, pressure alarms, hydraulic protection, and equipment interlocking in demanding environments.

Types of Pressure Switches

Pressure switches can be classified by sensing mechanism, pressure type, switching configuration, adjustment method, and operating environment. Common types include diaphragm, piston, bellows, and Bourdon tube pressure switches, as well as pneumatic, hydraulic, and water pressure switches. Options include normally open (NO), normally closed (NC), adjustable, fixed-set, high-pressure, low-pressure, waterproof, and high-temperature models. These configurations are widely used in hydraulic systems, pneumatic equipment, machine tools, lubrication systems, cooling circuits, and industrial automation.
