LED lamp for physics class

### LED lamp for physics class ###

Optical experiments can particularly excite students in physics lessons, especially if you have enough colorful lamps!

You only need three printed parts and a few components for this lamp. The structure is simple. If you are lucky, you will find a skillful student to help you assemble.

The lamp requires
• three printed parts (bottom part, top part, slits),
• a switch of the typ Wentronic S 103 (see pdf),
• two self-tapping screws DIN 7961 2.2x6.5 (for the switch),
• two pairs of battery springs (with 10mm width and 9mm height as well as a small, 7mm long soldering tag)

• two AA batteries,
• a small piece of wire and
• of course a LED in different colors.

The bottom part is the same for all lamps. All components are assembled in this. The photos should be meaningful enough.

I printed the lamp in the color of the LED (at least som
