SJE MilliAmpMaster™

Mechancially-Activated, Narrow-Angle or Wide-Angle Control Switch

Control switches accurately monitor liquid levels to activate pump control panels and alarms.

The SJE MilliAmpMaster™ control switch is narrow-angle or wide-angle control switch that offers control for AC or DC applications in potable water, wastewater and sewage.  The internal switching mechanism has seal gold cross-point contacts for reliable low current operation.  It features a blue colored cap for easy identification.

Common applications include PLC (programmable logic controller) panels, IS panels with intrinsically safe barriers, low current solar applications and other low current control panels and alarm applications.

The wide-angle version activates/deactivates at approximately 10.16 cm (4 inches) above and below horizontal with a 9 cm (3.5 inch) tether.  The narrow-angle version activates/deactivates at approximately 3.81 cm (1.5 inches) above or below horizontal with a 9 cm (3.5 inch) tether.

This switch is not sensitive to rotation.

Normally Open Models (high level): The control switch turns on (closes) when the float tips slightly above horizontal signaling a high level and turns off (opens) when the float drops slightly below horizontal. 

Normally Closed Models (low levels): The control switch turns on (closes) when the float tips slightly below horizontal signaling a low level and turns off (opens) when the float tips slightly above horizontal.
