Two round pin 12v socket

Will a two pin shaver plug fit the socket  round pin

I’m a big fan of the old 5a round pin sockets - tested them to 15a with no heating at all, despite having a much lower rating. 
 

Another option is Neutrik XLRs - the 4 pin variant is industry standard for 12v DC power in the broadcast industry, and is rated for 10a per pin. You can also get a 90 degree version so it doesn’t stick out as much.

I agree: for ready availability, visual acceptability (doesn't look like an item from a test lab) and current handling, the 5A round pin sockets are a good choice. And the cable lead-out at 90° is a benefit in space saving.

 

The Neutrik connectors are high quality, probably with a price tag to match. They are built for repeated plug-unplug actions, with a repeatable contact resistance. I think for most boaters, a device is rarely unplugged so often. Current handling given in the data sheet is most likely a breaking current, with the mated handling being higher.

 

With cheaper items, the breaking current and mated current are probably the same. I'm happy with my original choice of 12v connectors, and they come in 2-pole, with significantly better current handling.

NC4s are actually only £7 a connector, which is actually only £1-2 more than a decent BS546 MK branded 5a plug. It’s certainly a lot cheaper than the fused 5a plugs. They are harder to fit though as you need a soldering iron or the special crimping tool.
