"Sorry to sound like a techno-nerd but all of this stuff is important.".
Don't apologise, dude. You're right - it is important. No disrespect towards MFV1132, but what the heck are people thinking when they ask such a question in such a terse way? I didn't see any offer of explanation, or specifications, no clue for what said switch was for ... no nothing. So imagine how it must feel if you were the proprietor of a model-supply shoppe, and a possible customer walks in and sez: "I need a switch. Give me a bank of 'em.". What do you do? It gives me the spooks, because I'd be thinking to meself: "Hmm... and I wonder if the same attitude applies to his lakeside etiquette? Or even his driving?"
Well, you, you're obviously more polite. And, if you were indeed the proprietor, it means you'd have to worry about making a living to pay the mortgage, keep the chap happy, give him what he think he wants and send him on his merry way.
Me, on the other hand, I'd be tempted to fob him/her off with an itsy-bitsy 2-Amp job, even when I KNOW he/she will be shoving 15-Amps up the sucker, just so that he/she would come back, hopefully with a bit more knowledge, and explain what it is he/she is trying to do. That surely would make the life of any proprietor miles easier. Mayhem members, too.
Did you read the one where I did a short stint in the chokey because I refused to cough-up for that poll-tax thing? In there one soon learns that if you don't ask, you simply don't get. Same rule applies in Freedom Street... if you don't ask the right questions, you can't really expect any help.
Just Rx'ed your PM, Dave Jacket.
