This package contains the basic float switch and wiring to get started. It requires the SwitchPak to interface with the GrowPak system. Available in single, single with mount, and double with mount. Also available is the Switch Cable Kit. The Switch Cable Kit offers you replacement cables for the Sero Systems SwitchPak. Hook up extra floats switches, flood alarms, or other types of triggers with a Switch Cable Kit.
I ended up buying this product after I read great amount of reviews, but Switch Adapter Kit is top.
