The SJE MilliAmpMaster™ control switch is narrow-angle or wide-angle control switch that offers control for AC or DC applications in 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 4 inches above and below horizontal with a 3.5-inch tether. The narrow-angle version activates/deactivates at approximately 1.5 inches above or below horizontal with a 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 level): 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.
