Standard float switches with one switching point

Standard float switches with one switching point

Our standard float switches based on a reed switch have a switching tube diameter of 12 mm. The potential-free reed switches may be actuated by a permanent magnet which is integrated in the float body and moves on the tube depending on the level.

The switching process itself is contact-free and works by magnetizing the pair of reed blades (made of ferromagnetic material) which are located in a hermetically sealed glass tube of the reed switch.

The switching function always refers to a rising or falling level.

The switching outputs can be defined as needed, either as NCC, NOC or change-over contact.

A float switch generally consists of a connecting head, a switching tube, the switching function and the float. The float switch is easy to install as the connecting head can be perfectly adapted to suit your needs.

A combination of temperature and level measurement allows for a perfect monitoring and control in a consuming point.
