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 inch (10.16 cm) above and below horizontal with a 3.5 inch (9 cm) Tether. The narrow angle version activates/deactivates at approximately 1.5 inch (3.81 cm) above and below horizontal with a 3.5 inch (9 cm) Tether. It is not sensitive to rotation. Normally closed 1016182 (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.
