The Switchgenie 12 is an electronic pressure switch for up to 12 bar with simple adjustable digital cut in/cut out pressure settings, overload protection and an integral pressure gauge to control a pump up to 2.2kw (16A) single phase.

It also provides smart pump run dry, over-current and rapid cycling protection and can be set up to control two pumps as a pair and alternate operation with an LCD display to show either operating or set pressure values and an alarm light to indicate if there is a system fault.
