Float Switch Specifications

SJE MILLIAMPMASTER
™
Control Switch
SPECIFICATIONS
Mechanically-activated control switch designed to activate low current control panels and alarms.
This wide-angle or narrow-angle control switch offers reliable low current control for AC and DC applications
in water, wastewater, and sewage. The internal switching mechanism has sealed gold cross-point contacts for
reliable low current operation. 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
alarms applications.
The wide-angle version activates/deactivates approximately 4" (10.16 cm) above and below horizontal with a
3.5" (9 cm) tether. The narrow angle version activates/deactivates at approximately 1.5" (3.81 cm) above and
below horizontal with a 3.5" (9 cm) tether. It is not sensitive to rotation.
Normally Open Model (high level)
The control switch turns on (closes) when the switch tips above horizontal signaling a high level, and turns off
(opens) when the switch drops below horizontal.
Normally Closed Model (low level)
The control switch turns on (closes) when the switch drops below
horizontal signaling a low level, and turns off (opens) when the switch tips
above horizontal.
