basic circuitry manual recommendations?

[La Bricoleuse]

I'm teaching a short class on introductory circuitry, super-basic simple stuff like putting together a battery-powered toggle-switch that turns on a light. I'd like to recommend a book or two to my students for basic electrical reference--something they can read through and hopefully learn how not to electrocute themselves or set things on fire.

Trouble is, i taught myself this sort of stuff from ancient books borrowed from my dad, and have no idea what might be new and available on the subject that they could, say, order from Amazon or pick up at the local bookstore.

Does anyone have any titles to recommend?

The students will be in the 25-30 age range, so ideally not something aimed at intrepid teens.

I didn't put this in Textual because it's not about novels or historical books, so forgive me if it's out of place. I figured it has more to do with making than reading, really.

You may be able to find Alfred Morgan's "The Boy Electrician", originally published  in the early 20th century.  Way steampunk, covers making an electric train, a wireless telegraph, batteries, photocells, thermopiles, the list goes on.  Full of references to materials obtained from the local blacksmith, purchasing bars of selenium at the pharmacists, etc., but you won't find a more basic work on electricity from the ground up (couldn't help myself).
Slightly more current (ahem) is the "Engineer's Notebook" by Forrest Mims, I think Amazon has it.  Very introductory on basic electricity, analog and digital circuits.
There is a canonical work called "The Art of Electronics" by Winfield Hill that no designer would be without.  Over 1000 pages of amazing reference, but a bit pricey for beginners.  Nice to have a copy for your advanced students (bent on world domination).
Freebies are available on any of the BEEM Robotics sites.  Small, low power, yet sophisticated results.

Do you have a link for this? Forgive my ignorance, but googling "beem robotics" isn't producing any obvious results. Thanks for the other recs!

I should clarify, too, that the class is nothing "steampunk related"--it's intended to address the incorporation of circuitry into wearable objects (for example, a dress that has LEDs integrated into its construction).

A bit more than what you're looking for, but there are some excellent online classes I keep meaning to take from the www.ARRL.org website.  There are classes that cover basic analog and digital electronics all the way up to a fairly decent level of knowledge.  While I know you're teaching a class and not looking for one yourself you may want to check their site to see what texts they use.

Sorry, i mistyped, should be BEAM robotics.  A survey site is at www.solarbotics.net. 
Should be able to swap LEDs for the motors to achieve some interesting dynamic effects.  Most BEAM designs are centered on very low power & solar schemes, sounds great for clothing (who wants to recharge a blouse?).
