A Small Pressure Switch operates by sensing pressure in a system and activating or deactivating an electrical contact at a preset pressure point. When system pressure reaches the set threshold, a diaphragm or piston inside the switch moves, mechanically actuating a microswitch. This opens or closes the circuit, sending a control signal to start or stop pumps, compressors, or alarms. Its compact design makes it ideal for applications where space is limited but precise pressure monitoring and control are essential.
