The Twin Float pump switch consists of two floats, each float contains our standard "JH" series switch. The boot contains a heavy-duty latching relay, which enables the floats to function together. The relay eliminates pump chatter in turbulent conditions.
The unit is well suited for narrow and deep sump pump pits. On the N.O. (pump down) model, the pump is turned on when activated by the top float switch. The pump stays on until the bottom float switch turns it off, this allows a pumping range of about 60" with the standard 60" cord length on the bottom float. This can be extended almost indefinitely with longer cords.
