摘要： Disclosed herein is a safety switch including a tube that is capable of shrinking when exposed to temperatures in excess of a predetermined temperature level (“heat shrinkage tube”), wherein the length of the heat shrinkage tube is changeable to control current conduction, one end of the heat shrinkage tube is fixed, and the other end of the heat shrinkage tube is connected to an electric wire connection part, such that current conduction or current interruption is accomplished by the change in length of the heat shrinkage tube when the heat shrinkage tube is varied due to heat. When a battery or a battery pack is exposed to an abnormal environment, with the result that the temperature of the battery or the battery pack exceeds a predetermined temperature level, the heat shrinkage tube of the safety switch shrinks to directly interrupt external charge current, thereby preventing the further charge of the battery or the battery pack. Furthermore, internal energy accumulated in the battery cell is forcibly consumed, thereby fundamentally preventing the progress of the abnormal operation of the battery or the battery pack. Consequently, the safety of the battery is secured.
