Single-Point Level Switch

Single level float switches for horizontal and vertical installation are used for the level monitoring and the level display of liquids. With their robust and maintenance-free construction from steel or plastic, they are suitable for almost all liquids. They can be used to trigger visual and audible alarms, to control pumps or to activate “emergency stop” functions.

The details listed correspond to the maximum possible specification according to the product options.
