Level switches can be used in multiple configurations. See examples below.
A single low level switch can be used to shut off the pump if the fluid level gets too low.
A single high level switch can be used to shut off the pump if the fluid level gets too high.
Use both the high an low level switch together. The high level switch can send a signal to an
external alarm. The low level switch can shut off the pump.
Or - connect the switch to any external device; such as
an alarm or siren.
