I have installed two Marinco 30amp 125volt ac receptacles, one on each side of the boat.
I now require a selector switch that I've seen at sometime on the 'net but have no information regarding the make, name, description etc.
The product I saw was a small, compact cylindrical, three position switch having a faceplate worded: Port-Off-Stbd.
If anyone has any information on this product & wher it might be available, I would certainly appreciate hearing from you . . . Bob T.
