Two switch installation (providing low level cut out protection)

For installations where an erratic water supply can be a problem, two switches can be

used as illustrated. Float switch 2 is controlling the start and stopping of the pump, whilst
float switch 1 is providing low level protection by preventing the operation of the pump in
the case of water shortage.
