The F4 series adjustable pressure switch provides an electrical signal once a set pressure value is reached.
Preset pressure is adjusted by rotating a screw, located in the centre of the switch, clockwise to increase pressure and anti-clockwise to decrease pressure.
This range has a a changeover contact which allows the pressure switch to be used in a normally open or a normally closed condition.
The F4 adjustable pressure switches are suitable for pneumatic, hydraulic and many other applications.
Note: To rotate the screw a 2mm allen key is required. Mechanical stops protect the spring and micro-switch from over pressurisation.
