Abstract
An electrosurgical return pad including a material backing configured to support first and second conductive materials and an insulative layer disposed therebetween. A switch element is mounted on the first conductive material and is activatable upon reaching a threshold condition, such as temperature. Upon reaching the threshold condition, the switch element automatically activates to provide electrical continuity between the first and second conductive materials to offset the threshold condition.
