1. A keyswitch comprising: a key having a plunger coupled thereto; chassis means for supporting said plunger in an actuatable manner; a first conductive planar sheet member having a planar springlike pattern formed therein, said pattern comprising a plurality of concentric pairs of appertures therethrough with adjacent pairs of apertures having increasing radii from a common center portion, the apertures of each pair being circular arcs of equal radii and less than 180* but greater than 90* wherein alternate pairs of apertures are rotated approximately 90* with respect to each other about said common center portion which is defined by the innermost pair of apertures; spacer means arranging said common portion in compressive contact with said plunger for maintaining said plunger in an unactuated condition; a second conductive member oriented below said common center portion; an electrically insulating member for normally separating said second conductive member and said common center portion but permitting said common center portion to make electrical contact with said second conductive member when said common center portion is forced through the plane of said electrically insulating member by said actuated plunger.
