Introduction: ON-OFF Switch Bow

This is an idea if you want to add an ON-OFF switch to a wearable electronic garment without adding a mechanical switch.

You'll need:

1. Conductive tape (you can find it here). This tape has the peculiarity of having steel fibers mixed with polyester fibers.
2. Scissors
3. A low power electric/electronic circuit you want to turn on and off


Step 1:

Cut two pieces of tape, each one about 12 inches (30 cm) long. They might be longer if desired.

Connect one end of the first piece of tape to a power generator or battery, 5V is enough. Connect one end of the other piece of tape to the other pole of the battery/generator i.e. via an LED.  See picture.

Be sure you connected the LED with the right polarity.






Step 2:

Now tie the two ends together with a bow. The electricity will flow through the bow and turn you circuit on! To switch your device off, just undo the knot.

PLEASE NOTE: this is a switch for low currents and low voltages only!

Just to let you know the link to the tape is broken as they have moved, so it doesn't take the user to the product page anymore - I glanced but didn't see the tape, otherwise I'd include link, here's the new URL to the main site tho: http://www.plugandwear.com/

why don't you organize a workshop about e-textiles? we can supply all the materials + give you some training if necessary

I already teach a lot of art workshops, etextiles would be the next step.
