float switch...ATO help

[nate82]

If i bought this float switch http://cgi.ebay.com/Liquid-Level-Float-Switch-for-Aquarium-Auto-Top-Off_W0QQitemZ180285688620QQcmdZViewItemQQptZLH_DefaultDomain_2?_trksid=p3286.m20.l1116 how would I go about making an Auto top off for my 5.5 pico? I know (at least I think i do) that I won't be able to just plug a powerhead into it and go so does anyone know what else I would need or if i'd just be better off spending the 80 bucks(I really don't want to) thanks!
