Fox K4 Series Adjustable Pressure Switches
Fox K4 Series Adjustable Pressure Switches from Hydraulic Megastore
K4 adjustable pressure switches permit opening or closing of an electric circuit upon reaching a predetermined pressure value. The pre-set pressure is found by rotating the external screw located at the centre of the instrument clockwise to increase and vice-versa to decrease the pressure set point value.
Mechanical stops protect both the spring and the micro-switch from over pressurisation. The main characteristic of this series is that this miniature pressure switch can be totally dismantled.
