Hi there,
just thinking modding one of those solar pool pumps
http://www.ebay.com.au/itm/NEW-SOLA...60?pt=LH_DefaultDomain_15&hash=item4843136010
to pump wate from a drainage ditch/pond. Since it fills just some times I would put in two float switches and a relay to create a latching circuit like this
relay would be this

do I need something else since the pump may drain too much from the panel? I.e. something to switch it on when the voltage is more than 6V or so? Read earlier on a relay would do?
Thanks,
Case
PS: am aware the schematic is 12V and the ebay pumps are 6V....
