More details

The “K4” series adjustable pressure switches allow to open or close an electric circuit upon reaching predetermined pressure value. The preset 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. The screw is protected with a plug. Mechanical stops protect both the spring and the micro-switch from over pressurization.
