This week, I made switches, using paper.

First, I tried a momentary switch.(Fig.1) When you bend it, it will be turned off.

 Fig.1

Then I tried many other forms of paper switches.(Fig.2,3,4) But they didn’t work well. Because after the paper was folded, it can not be perfectly flat. Then it’s still an open circuit after the switch was turned off.

     Fig.2,3,4

Therefore, I kept working on paper switches like the 1st momentary switch. (Using bending). The 1st switch is a normal switch. (Fig5, 6).

      Fig.5,6

The second one is switches in parallel. When you bend the whole piece, you will make 6 parallel circuits open.

     Fig.7,8

The third one(Fig.9). There are two switches in parallel. When you bend it, Circuit A will be open, Circuit B will be closed.  When the paper is flat, A will be closed, B will be open.

Fig.9

The fourth one(Fig. 10,11) There are two switches in parallel.One is a digital switch, the other is a switch containing a bend sensor. When you bend it towards you, the circuit is closed without resistors. The light is bright. When you bend it backwards, the circuit is closed. The light is dim and the brightness can change.
