Claim 9:
10. The keyboard system of claim 1:
wherein the substrate defines an array of bores adjacent the array of inductors;
wherein the tactile layer comprises a set of discrete key elements arranged over the substrate and cooperating to form the tactile layer; and
wherein each discrete key element, in the set of discrete key elements:
defines a key face;
comprises an elastic post extending rearward from the key face;
is installed over an inductor, in the array of inductors, with the elastic post:
extending through a bore, in the array of bores, in the substrate; and
retaining the discrete key element over the substrate;

houses a magnetic element in the array of magnetic elements; and
is configured to compress against the substrate and to move the magnetic element toward the inductor responsive to application of a force on the key face, the magnetic element inducing current flow through the inductor responsive to motion toward the inductor.
