“F4” adjustable pressure switches allow a micro-switch commutation once a preset pressure value is reached. The set point is adjusted working on the central screw (P3 execution) or intercepting the regulation dowel situated inside the instrument, using a 2mm hexagonal key (M2 and M3). Rotating clockwise the set point is increased and vice-versa is decreased. Mechanical stops protect both the spring and the micro-switch from over pressurization.
Technical features:
Body: 24 mm hexagonal in zinc-plated carbon steel.
Working temperature: from -25°C to +85°C.
