Piston Pressure Switches

Piston pressure switches are mechanical devices that use a spring-loaded piston to sense changes in fluid pressure and actuate an electrical contact when a preset pressure level is reached. The piston moves in response to system pressure and compresses a spring, which triggers the switch at the defined setpoint. These switches are well-suited for applications involving hydraulic fluids, oils, and other non-corrosive media with moderate to high pressure.

In industrial environments, piston pressure switches offer a rugged and reliable solution for pressure monitoring and control. Their mechanical design provides excellent durability and resistance to vibration, making them ideal for heavy-duty use. They offer high cycle life, fast response time, and adjustable setpoints for flexibility across various pressure control applications.

Piston pressure switches are particularly valuable in systems where high proof pressure or overpressure tolerance is required. Their compact, robust design makes them suitable for space-constrained installations and challenging environments. They can be used in either normally open or normally closed configurations depending on system requirements and are available with explosion-proof or weatherproof enclosures.

Typical applications include hydraulic power units, lubrication systems, mobile equipment, machine tools, and industrial machinery where fluid pressure must be reliably monitored or controlled. Their ability to handle high pressures and endure demanding service conditions makes piston pressure switches a critical component in pressure-dependent process control and equipment protection.
