Vacuum switch 400 series

Product Introduction

The UE vacuum switch 400 series from the United States is a versatile UE pressure switch, particularly suitable for situations requiring multi-point output and control. The dual point and 3-point settings provide multi-point outputs, which can be used for alarm and shutdown, warning and alarm, high/low limit, and liquid level control functions.
