Classification: CPC F  H | IPC F  H

Claim 18:
19. An apparatus, comprising:
a heating element;
a contact plate;
a switch coupled to the contact plate, the switch configured to prevent a current from conducting through the heating element when the contact plate experiences a temperature equal to or greater than a temperature limit;
an urging element providing an upward force to cause the contact plate to contact an object placed on the apparatus, the contact plate configured to be positioned between the switch and the object when the object is placed on the apparatus, the contact plate comprising a thermally conductive material, the urging element comprising:
an urging portion coupled to the switch and providing the upward force; and
a deformable surface operatively connected to the urging portion and that mechanically deforms to cause the upward force in response to a downward force applied from the object to the contact plate, the deformable surface comprising a plurality of planar sections connected at an angle, the upward force applied through the deformable surface being a restorative force to urge the deformable surface to restore the angles between the plurality of planar sections; and

a housing configured to enclose an interior volume in which at least a portion of the switch and the urging element are positioned, the housing comprising: an open end; and at least one sidewall surrounding the interior volume and extending from the open end, wherein the at least one sidewall includes in inwardly facing surface facing the interior volume, wherein the inwardly facing surface extends in a direction perpendicular to the open end from the open end to a second end opposite the open end, and wherein the inwardly facing surface is perpendicular to the second end;
wherein at least one planar section of the plurality of planar sections includes an outwardly facing surface in contact with and coupled to the inwardly facing surface of the at least one sidewall; and wherein the at least one planar section extends in the direction perpendicular to the open end.
