12 volt power socket installed in 177

Originally posted by CharlieM Bud, I've seen the Andersons advertised, but never seen one in person. How do they handle keying or polarity? Will two reds mate, two blacks mate, but not a red and a black? Or is it something else. Also have you ever seen a panel mount version? Any connector system to replace the cig plug will have to have a panel mount female and cable mount male.

The colors are simply to identify different "systems".  The colors have nothing to do with which ones mate with each other.  Standard is grey.  The same size of any color will mate, IOW no problem plugging a grey into a red if they are the same size.

Polarity is marked on them for DC systems. they really are someones great idea-  I like them a lot.
If wired correctly it is impossible to reverse polarity plugging them into each other.

The links in jjkd's post detail the physical design, although I admit I've never seen the single pole ones wikipedia shows, all I've used have been 2 pole.

No, if assembled correctly they will always maintain polarity correctness.   Each connector is marked as to which contact is positive on the two conductor ones.  I've never had a need to use the individual contact version since I've only used them on 12V DC systems where both + and - are needed.

Roll pins?   Lost me there.....haven't seen that on the ones I've used.
