Patent ID: 8777115

Claim:
An electronic card comprising: a sealed housing having a first surface and a second surface opposite the first surface; a switch member mounted within the housing adjacent the first surface and movable relative to the housing along an axis perpendicular to the first surface between a rest position and an actuated position; and an actuation member mounted within the housing and movable relative thereto along the axis, the actuation member having a stem, an annular spacer concentric with the stem and spaced therefrom, a rim surrounding the stem, at least one arm extending radially between the annular spacer and the stem, and an actuation surface adjacent the second surface of the housing and a contact surface opposite the actuation surface and adjacent the switch member, the actuation surface comprising an upper surface of the stem and the contact surface comprising a lower surface of the stem; wherein, upon application of a pressure on the second surface, the pressure is applied on the actuation surface, thereby displacing the actuation member along the axis with the contact surface exerting the pressure on the switch member and moving the switch member from the rest position to the actuated position.
