Pressure switch STANLEY 152077XSTN — single-pole pressure control for compressor systems

STANLEY 152077XSTN is a single-pole pressure switch designed to control compressor and pneumatic systems. It senses system pressure and opens or closes an electrical contact to start or stop a pump or compressor, enabling basic automation of pressure regulation and safety cut-off functions in workshop and light industrial equipment.

Advantages

This pressure switch provides straightforward pressure-based on/off control with a single electrical pole for simple installations. The design enables integration into compressor systems to maintain set pressure levels and protect equipment from overpressure or loss of pressure. Its compact form factor and mechanical switching action offer reliable operation in typical workshop and maintenance environments where electronic controllers are not required.

Suitable for

• Control of small to medium workshop compressors
• Automation of pumps in pneumatic or fluid systems
• Safety cut-off for pressure vessels and air tanks
• Retrofit or replacement in existing compressor control panels

Key specifications

• Type: single-pole mechanical pressure switch for compressor control
• Function: on/off switching in response to pressure changes
• Application: compressor and pneumatic system pressure regulation and safety cut-off
• Mounting: panel or pipe mounting compatible with standard compressor installations
• Operation: mechanical actuator with adjustable setpoint (where applicable)

How to use

Install the pressure switch in the compressor or pneumatic line according to the system layout, ensuring correct orientation and secure mechanical connection to the pressure port. Connect the single electrical pole and common terminal to the compressor motor starter or pump control circuit following electrical safety standards and the system wiring diagram. Adjust the pressure setpoint and differential (if the device provides such adjustment) to match the desired cut-in and cut-out pressures for your system. After installation, test operation through multiple pressure cycles to confirm reliable switching and correct integration with safety and control elements.

Usage recommendations

Verify compatibility of pressure range and electrical ratings with your compressor or pump before installation. Use proper sealing and avoid over-tightening on pressure ports. Perform periodic functional checks and clean or replace the switch if signs of mechanical wear or contact corrosion appear.
