Coelbo Switchmatic 2 electronic pressure switch

The Coelbo Switchmatic 2 electronic relay is designed to control and protect surface or borehole pumps with power up to 2.2 kW. It is an innovative development from Coelbo and holds an international patent.

The pump control principle is similar to the operation of a traditional electromechanical relay with a spring, but it is a 21st century technology, as it has many advantages compared to a conventional electromechanical relay with a spring.

An additional advantage of the Switchmatic 2 electronic relay is that it can be used in water supply and pressure boosting stations assembled on 2 pumps.

Advantages of the Switchmatic 2 relay:

• 2-in-1 device – controls and protects the pump from adverse operating factors
• dry-running protection
• overload protection
• ART function – auto-restart after water supply is restored
• allows you to set the on/off pressure with an accuracy of 0.1 bar
