Pressure switch 2

Body size envelope: 14 X 14 X 7 mm Components 1. Casing with nozzle 2. Bellow 3. Disk 4. Spring • Air enters the at high velocity initially if pressure is more than required it will be more Sensitive With high velocity air • As air flow increases the disk will be pushed , the bellow expands • When disk moves it activates the circuit • When air pressure decreases then the energy stored in the spring pushes the disk to its initial position so that the circuit will breakup.
