ABSTRACT OF THE DISCLOSURE Apparatus adapted for cooperation with the human foot for performing a switching function in response to ambulation. A substrate is provided with a generally cen- trally located contact. Posts extend from the substrate and space a flexible disc from the contact while allowing the central portion of the disc to flex into electrical com- munication therewith. The assembly may be positioned in the heel portion of a shoe insole so as to switch between open and closed positions as weight is placed on the heel and re- moved, as in walking. The switch may be employed in as- sociation with muscle and/or nerve stimulators for objectives such as combating foot drop or providing hip stabilization. In addition, proper selection of the flexible disc and post spacing will provide a normally open switch which will close when a preselected limb load has been applied. Also, the apparatus may be made bi-directional such that the same insole assembly may be employed with either foot.
