Liquid Level Switch - RSF70 Series

The RSF70 series is designed for external mounting, achieved with a high grade compression seal. This avoids the need for access to the inside of the chamber and is ideally suited to applications where space or fitting time are prime considerations.  

They are manufactured in a variety of materials, with a choice of gasket materials, to suit most commonly used liquids.

The switch action may be reversed by rotating the device through 180°. 

Typical applications include auxiliary tanks on vehicles and commercial dishwashers.
