View full detailsOverview:
Pump-Duty float switches used in residential septic systems are typically rated for around 13 amps and control power directly through an internal switch to your effluent or solids pump and typically come in two types:
Normally Open:
Normally-Open float switches default to the "open" state in which power cannot flow through the float switch. So until the water level in the septic tank rises to lift it up, your septic pump will remain off.
Normally Closed:
Normally closed floats default to the "closed" state in which power can flow freely through the float switch. Typically this means that when the float has been raised up by high effluent level, the septic pump will not receive power.
Typically, pump-duty floats will be wide-angle, meaning that the angle required to engage and disengage the pump-duty float will be approximately 90 degrees, vs something like 15 degrees with narrow-angle floats.
