LongWire controllers are an upgraded version of our standard controllers. They feature a low voltage float switch circuit with removable float switches that have longer wires.

You need float switches with a JST connector to mate to the controller (listed below). If you'd like to connect your own float switches check out the assembled DIY controller on our misc page.

Mounting Brackets Sold Separately!

LongWire Single
One JST float switch connector
$30
LongWire Double
Two JST float switch connectors. One float switch sets your water level, the other acts as a fail-safe.
$31
LongWire Triple
Three JST float switch connectors. One float switch sets your water level, the other two float switches act as fail-safes.
$32
LongWire Quad
Four JST float switch connectors. One float switch sets your water level, the other three float switches act as fail-safes. You can also reverse the operation of a float switch for run-dry protection by installing the float upside down on the float switch.
