Abstract
A very low touch force keyboard, employing soft conductors, preferably conductive fabric, disposed in a keyboard grid. The grid rests upon a soft substrate, and has soft spacers separating the two axes of the grid, arranged to allow conducting portions of the grid to contact each other when soft, fabric-like keys are pushed. The grid conductors are electrically connected to a keyboard controller.
