I am attempting to connect a Rule 500 Bilge pump installed in my Cohasset II to the switch that has been sitting dormant on my console. The pump has been wired directly to the battery for most of its service life, and if possible, I would like to use the current rocker switch that is a marine grade single pole single throw (SPST) on/off type switch. Generally, the pump works fine, but I would like to be able to override the float to clear the bilge from time to time. Unfortunately, I do not have the directions from Rule. Three Wires...Black to the Battery negative, brown to battery positive (on a blue sea fuse panel)and the brown with white stripe has always been capped. Can I use this switch or do I need another type for this application. Thank you in advance for your help.

Wire the console switch in parallel with the float switch.

Brown with white stripe to dash switch. As jim suggests, that will
parallel the float switch and the dash switch. Either one on
and the pump will run. If you also connect that wire to
a light bulb whose other side goes to ground, you have a
bilge pump pilot light that will come on when either switch
is on.
