It is a micro pressure switch with a waterproof terminal block that uses a robust aluminum die-cast cover and is ideal for liquid level control (level switch).
It is also ideal for detecting wind pressure from blowers, etc.
As a general rule, the pressure setting is the factory setting. When ordering, please specify the operating pressure value (ON, OFF) and port size .
