Further product information
Two different plastic versions make it possible to realise many industrial applications. The switch is characterised
by its maintenance-free design, the small dimensions and the reed contacts with high switching capacity. The switch is installed in the side of the container. A plastic float with a welded-in magnet moves up and down on a hinge through the liquid level. In the end position, the cast-in potential-free reed contact is actuated by the magnet. The switching function (normally open/ normally closed) results from the installation position. Simply turning the switch by 180° reverses the switching function.
