I get a lot of little packages where HS tubing, metal rods, etc. are packed like gun barrels. It would take a only a few seconds of thinking to minimize the shipping charges. I also try to stop big, expensive printed catalogs, when I use the Internet almost exclusively. What does Digi-key's 2800-page catalog cost? Somebody is making $$$ off this waste. -------- Eric M.

Seems like this will do all of the switching for you. Also, have you considered the stick grip from Tosten Manufacturing , perhaps linked up to a TCW Safety-Trim box?

Living in the hinterlands, I get a LOT of stuff delivered to my mailbox and front porch. Yeah, from time to time I get a tiny what'sit in a big box but in the grand scheme of things I find that most packaging is appropriate to the task. Go watch the folks at the shipping tables of an operation like Digikey. Digikey has UPS and FEDEX airplanes sitting at the Thief River Falls International Airport awaiting just THEIR shipping tasks for the day. To suggest that these or similarly engaged folks are institutionally or environmentally irresponsible is something of a stretch. The reason we shop with those folks is because they're fast and priced at a level we're willing to pay. To put some "click box" generated wrench in their flow of tasks to satisfy what is probably the wishes of one customer in 1000 is . . . well . . . It's a free market. If you don't like the way some supplier is treating you . . . find a more pleasing supplier . . . >I also try to stop big, expensive printed catalogs, when I use the >Internet almost exclusively. What does Digi-key's 2800-page catalog cost? You can go to your profile in Digikey and shut off the paper catalog mailings. I got a 6-pounder from Mouser yesterday, got to get that shut off too. At the same time, the paper catalog is exceedingly useful to some customers when doing comparison shopping . . . you and I go to the website and punch in a number . . . we already knew. But when it comes to browsing the constellation of choices, thumbing through the pages is hard to beat. Catalogs are also a huge teaching tool for the neophyte purchaser. You have illustrations, descriptions, specs, prices, jargon . . . all those mystifying things surrounding electro-whizzies that have to be learned. And you get it all in a FREE textbook. >Somebody is making $$$ off this waste. Lots of folks are making money keeping a lot of customers coming back for exemplary service and quality. Pushing our judgements of "waste" onto their activities can be a consideration for picking amongst the various service providers. But to launch a crusade based upon that judgement is counter-productive and guaranteed to be ineffectual. Bob . . . >-------- >Eric M.

From: "jonlaury" When I was figuring out my ground power jack switching, I thought that it would be nice to have a test function in the switch to protect my electrical system from inadvertent reverse polarity or excessive voltage. So, nevermind that Bob's design took all this into account, I got a cool Honeywell switch that is a 3 position, MOM-MAINTAIN-MAINTAIN. My myopia became apparent when I was doing my wire book page for this circuit and I saw that the "test" function (MOM position) did nothing different than just throwing the switch for GP function. If something was amiss, per Bob's design, the 2a breaker fries and you investigate. So my question to the group is , What else might I use the MOM function of the switch for, other than to connect it to my brain to push ON before I start thinking about cool ideas.
