Operation
Monitoring liquid levels in small tanks, sumps, or machinery enclosures can be difficult when space is limited. The LR21 horizontal finger float switch mounts through the side wall of your tank to provide precise high or low level detection without obstructing internal components.
Operating via a clean reed switch mechanism, the float arm rises and falls with the water level to close or open the electrical circuit. It comes complete with an M16 thread, fixing nut, and sealing washer to ensure a reliable, leak-free installation.
