Looking for battery selector knob

[Ctmangrum]

Trying to find a battery selector knob for 1976 2896 Mariner. Don't know where to even start. Strictly for the looks. Thanks.

Post a pic of what you have. There were only a couple different manufacturers. Perko was used frequently back then.

Welcome to the forum.....my advice get a brand new switch, the contacts will be well worn etc if it is the original, there are better design switches now, make before break etc.......good luck with your up grade...

Never got notified I had a response. Here is a pic of the front of the switch that broke. Didn't snap one of the back. Has 4 terminals.

That's interesting. Never seen that style before.

Was able to find a similar one, but it's on a UK site:

I wonder how the diameter and mounting hole spacing matches up to the round Perko switches?

Funny.

AFTER I posted that I poked around just a bit and found TWO of those exact switches on EBAY. Called "Vintage Perko Switch"!

There were more too, they just get more expensive.

Really appreciate it. Didn't know it was Perko

What did you actually search for? What keywords did you use?

On ebay, I just searched for "vintage perko switch". I did an image for "vintage vapor-tight marine switch" at one point and I think that's where I got a clue it was an actual Perko. I was leaning to it being something a previous owner had upgraded and I couldn't find anything like it, until I stumbled on one in that UK site but those didn't have the "vapor-tight" label on the front. Looks like they used the same housing though.

I wonder if it also has a field disconnect on it? I think that would require 5 terminals though (or at least most that do have 5). Although, if it really had a field disconnect, then it probably wouldn't have that "stop engines before switching" warning on the front.

Yea, post of pic of the back too.
