K5 adjustable piston pressure switches activate a micro-switch once a preset pressure value is reached. The pressure is adjusted by rotating a graduated knob or, for the economical version, by a setscrew located on top of the unit.

Both systems are supplied with a device that permits locking the desired set pressure. Mechanical stops protect both the spring and the micro-switch from over pressurization.
