Pressure switch (compressor cut-out) GERMAN Przełącznik ciśnieniowy wyłącznik kompresora 135

Mechanical pressure switch GERMAN Przełącznik ciśnieniowy wyłącznik kompresora 135 is a compressor cut-out device designed to monitor and control air pressure in compressor systems. The unit operates by actuating internal electrical contacts at predefined pressure levels to start or stop the compressor motor, providing automatic pressure regulation and basic overload protection for workshop and industrial air systems.

Advantages

The pressure switch provides a simple mechanical design that is easy to install and maintain. It offers consistent actuation at set pressure points, ensuring repeatable control of compressor cycling. The robust construction suits workshop environments and moderate industrial use, delivering reliable pressure monitoring without complex electronics. Compatibility with common compressor configurations makes it a practical choice for routine pressure control tasks.

Suitable for

• Workshop air compressors for tools and pneumatic equipment
• Small to medium industrial compressor systems requiring automatic cut-out
• Compressed air stations where fixed pressure control and motor protection are needed
• Repair and maintenance projects replacing a mechanical pressure switch

Key specifications

• Function: mechanical pressure-actuated electrical switch for compressor cut-out
• Application: monitoring and control of air pressure in compressor systems
• Actuation: switches electrical contacts at preset pressure thresholds
• Design: compact, panel- or pipe-mountable housing suitable for workshop use
• Connection: standard electrical terminals for integration with compressor starters or contactors

How to use

Install the pressure switch in the compressor’s pressure line or on the receiver tank according to the system layout, ensuring correct orientation and secure mechanical connection. Wire the electrical terminals to the compressor starter or control circuit following the system wiring diagram and local electrical regulations. Adjust the setpoint and differential (if adjustable) to the required cut-in and cut-out pressures using the manufacturer’s adjustment mechanism. Verify operation by running the compressor and observing correct switching at the selected pressures.

Usage recommendations

Regularly inspect the switch for signs of wear, corrosion, or loose electrical connections. Periodic functional tests and calibration checks are recommended to maintain accurate cut-in/cut-out pressures. When replacing an existing switch, confirm compatibility with system pressure range and electrical ratings before installation.
