Hi Jim
I would reccomend the Yamitsu 4 way switch box, These seem to be quite popular with a lot of koi keepers. As for the power consumption of 485 watts on your pond i see no problem in useing one of these Yamitsu 4 way switch boxes, One of the switches is rated to 1,800 watts and the remaining three are rated to 500 watts each. Each circuit is independtly fused with its own LED testing button so you can be sure that the circuit is working.
Hope this helps.
Regards Shaun F.
