This are different contact switches made by students @BurgHalle #StickDirDeinInterface
You need to Layers of conductive textiles seperated of a layer non conductive textile like foam. The non conductive Layer need some holes in it, so if you push at the Layer Sandwich the conductive layers will touch between the holes in the non conductive textile.
this is an example for a simple contact switch.
step 1 – two layers conductive materials attached parallel
step 2 – seperate these layers with foam or something similiar with holes in it.
step 3 – fold up so that the layers are on top of each other.
ready to use!
