Ooops,
Does that mean I'm going to have troubles when I try to rewire my trailer with LED's and use the switches I bought that have the little LED indicators built into the buttons?
That depends. Most 12v "indicator light" switches have three posts/connectors: a line voltage post, a post for the wire heading off to the electrical load (the light or appliance), and a "ground" post, so it actually operates two circuits in parallel, th indicator light circuit and the load/appliance circuit.

Yep, that's what I got, those will do for most my circuits then.
I'm hoping I can find something similar in a 3 way switch for the porch light then.
Thank you

After several people commented that they liked my installation, but would add an "indicator" light that would light up next to the switch when the porch light is on.

Lynne thought that was a pretty good idea, so . . .

I bought a pack of bright blue LEDs that had been pre-wired with a resistor for 12v use and wired it up. I didn't even have to cut a hole in the fiberglass for the indicator light! The LED is bright enough that I was able to mount it on the backside of the fiberglass wall so that it points outward, and the light is bright enough and the fiberglass thin enough that the light shines right through. So now we have our switch and an indicator light.

The LEDs came in lots of 20, so I have lots of spares. If any one wants one, let me know.

Peter, you ARE coming to the June Meet aren't you....? What about the one in Canada this May? In either event (if you come to one or either) bring two or three of these set ups with you. I know I want to do add this item to our Trillium too.

Doug, with all the things you want to talk to me about, perhaps I should describe myself so you can figure out who I am when we show up at the Washington State Gathering.

Truth is I look a lot like Donald Trump. I'm a little shorter and thinner and have dark hair and eyes and a medium complexion instead of blond, blue, and fair. I'm younger and usually more casually dressed, and I have a little more hair up-top, so I comb my hair differently because because I don't need a funky comb-over. Oh, yea, he has a funny Boston-New York hybrid accent, where mine is a funny British-California-Ontario mix.

That should make it easy to find me when we arrive.

Good idea to use a three-way switch. I have done that in the past using standard home three-way light switches, available at any hardware store. We like the new style rectangular flat wall switches rather than the older style, but both work the same way. The upside is that I can have a bank of switches all together for my 110V and 12V lights (the same switches work on both voltages) and a 110V electrical outlet that look compatible. The disadvantage is that you need a larger cutout than for a little electronics type switch. This picture shows what I mean, from our previous Boler renovation.

I also like your LED indicator light idea, and will shamelessly copy it when we do the new trailer in the spring..

Any idea why these are called three-way switches when there are just two ways to operate them?

I had a four-way installed to control some outdoor lights. I think it's so the electrician can bill you more.

Regards,

Matt

It has to do with the number of wiring terminals. 3-way switches have three, 4-way switches have four.

To wire up a light that has two on/of switches, you use two 3-way light switches. The first 3-way switch is wired so the house's "hot" wire connects to the "load" terminal, and the two "pole" terminals are wired to the other 3-way switch's pole terminals, and the second switch's "load" terminal goes to the light:

hot wire-----3-Way====3-way-----light

To wire up a light that has three or more light switches, you wire a 3-way switch at either end, but insert however many 4-way switches you want in the middle:

hot wire-----3-Way====4-Way====4-Way====3-way-----light
