Abstract
A pressure switch and method of manufacture wherein a resiliently yieldable intermediate open layer is sandwiched between flexible conductive layers, all of which is enclosed between flexible outer layers, so that in the unstressed or relatively unstressed condition the contact layers are spaced apart by the intermediate layer, while flexure or other sufficient stressing of the assembly effects contact of the contact layers through the open intermediate layer.
