SPS13 High Current Pressure Switch

SPS14 Pressure Switch for Water Purifier

SPS15 Extended Duty Pressure Switch

^{Working Principle of Small Pressure Switch}

A small pressure switch operates by sensing pressure in a system and activating or deactivating an electrical contact at a preset pressure point. When the system pressure reaches the set threshold, a diaphragm or piston inside the adjustable pressure switch moves, mechanically actuating a microswitch.

This action opens or closes the circuit, sending a control signal to start or stop pumps, compressors, or alarms. Its compact design allows for easy integration in equipment where installation space is limited, while still maintaining precise pressure monitoring and control. Anwoll's small changing pressure switch combines sensitivity, stability, and space‑saving functionality.

^{How to Select the Right Small Pressure Switch?}

Determine Pressure Range

Choose a range that covers your system's maximum operating pressure (e.g., 0–10 bar for general industrial use). This applies to all types of small pressure switch models, regardless of size.

Setpoint Accuracy

Select ±1% FS or higher precision for critical applications. Even in a space-saving compact pressure switch design, accuracy remains essential for reliable switching.
