Standard float switches with three switching points

Standard float switches with three switching points

This design is an upgrade of the float switches with two switching points.

In some cases, it is not only the minimum or maximum filling level that is measured but there is also a need for a pre-alarm.

This pre-alarm gives the user the chance to fill up a tank with an additive, for instance, before the production process is interrupted.

Our float switches with three switching points meet this challenge.

Your wish is our command.
