HOW TO ORDER

K4 adjustable pressure switches permit opening or closing of an electrical circuit upon reaching a predetermined pressure value. The preset pressure is found by rotating the external screw located at the center of the instrument clockwise to increase and counter-clockwise to decrease the pressure set point value. Mechanical stops protect both the spring and the micro-switch from over pressurization. The main characteristic of this series is that this miniature pressure switch can be totally dismantled.
