This Festo pneumatic pressure switch allows an electric circuit to be closed or opened by air pressure. The switch will close when the pressure on the internal diaphragm rises above 2 bar and will open again when the pressure drops below 0.5 bar. The difference in the triggering amounts (hysteresis) reduces the chance of false signals occurring. Connect the air line using a standard G 1/8 connector. The switch has integrated wires for protection against dust and water splashes, earning it an IP65 rating.

Pressure Switches

Compressed air whilst generally considered a safe source of energy must always be treated with caution and under no circumstances be used for any other purposes than that for which it is intended.
