Level switches for external installation are used to monitor and control liquid levels primarily in closed tanks. Marine applications are subject to harsher operating conditions. Therefore, the components and devices to be used must undergo a type approval test.

Each AM switch is equipped with a display, which is even easy to see from various lines of sight. The contacts can be infinitely adjusted on the scale plate. They are activated by the magnetic system integrated in the float. There is a large selection of contacts available for various applications. The MKS-1/W-L-24V contact model is equipped with an LED.
