This micro switch makes it possible to realize a significantly higher electrical output though having a longer working life. The electrical and water-hydraulic components of the flow switch are completely separated.The construction of the flow switch allows mounting the electrical parts independent of the hydraulic components within the series production process. When fitting together chassis and switch box both parts of the flow switch are connected again. Due to the mature engineering low switching points are realized in spite of maximum water quantities. The pressure drop within the flow switch is only 1.5 bar at 30 l/min.Without waterflow With waterflowThe floater is in resting position. The contact is open.The floater is in working position. The contact is closed by the magnetic floater. Functional principle of a flow switch3/8\vertical mount. Cable 1,200 mm. Contact 1 A - 250 V. 1.8 l closed. 1.4 l open.
