Description:

For this flap switch, pull the tab out to open the flap and turn on the LED. The LED is attached to conductive fabric on the front, and fed to the back through the hole for the popup flap. It is then connected to conductive thread on both the positive and negative sides. One thread runs directly to the positive side of the battery and the other (negative) runs to the opening for the pull tab. The tab has a small, strategically place piece of conductive fabric sewn to it; the thread coming out from the back of the tab is attached to the negative side of the battery. When you pull it to a certain point, the conductive fabric and thread touch and complete the circuit.
