Question:

Thanks Kevin, I looked at the information and I have one more question. The instructions with the pump (Seaflo SFDP1-30-045-33) call for it to be fused with an 18 amp fuse. The switches you suggested say 10, 12, 16 amps. Is that a problem? Should everything on that line be 18 amps? What do those switches mount into? Is there an electrical box and a face plate made for it?

Yes, the Single 12V Rocker Switch # 37213405 is exactly what you need to power your water pump on and off and can be easily spliced in-line.

We also carry the Single Rocker Switch # 37212525, which has an illuminated switch to easily show you when power is running to the pump.

You would simply need to splice in a fuse holder like # SWC9539 between the switch and the Seaflo Diaphragm Pump for Boats and RVs # SE58FR. This fuse holder is rated for 20amps and will blow before the switch gets hit in the event of a short. To install the Single 12V Rocker Switch # 37213405 you would cut a hole the size of the body of the switch and the little plastic prongs on the top and bottom will compress as you push it in and pop out to hold the faceplate of the switch tightly against the wall.
