20120182116 | THERMAL SWITCH - A thermal switch comprises a first and second electrically conducting terminals and a pre-stressable electrically conducting connecting device such as a compression spring member. The connecting device, in a compressed state, contacts at most one of the first and second terminals, and, in a released state, electrically connects the first and second terminals. The thermal switch further comprises a retainer device retaining the connecting device in the compressed state. The retainer device comprises a retaining material that melts at or above a predetermined temperature for releasing the connecting device into the released state. In the compressed state of the connecting device, the first and second terminals are electrically insulated from each other by a hollow space formed between the connecting device and at least one of the first and second terminals. | 07-19-2012 |
