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 compact 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 pressure switch combines sensitivity, stability, and space‑saving functionality.
