K9 (1~400 Bar)

This adjustable pressure switch activates a microswitch once a preset pressure value is reached. The preset pressure is set by rotating the external nut clockwise to increase, and vice-versa to decrease the value. The nut is supplied with a locking device to stop the instrument once the pressure value is reached. Mechanical stops protect both the spring and the microswitch from over pressurization.
