Thermally-activated switch for short-circuiting a battery cell

摘要

A thermally activated short-circuit switch for connection in parallel with a battery cell has first and second contact elements (6; 3) which are distinct from the electrodes of a diode, and thermally activatable means (45) for short-circuiting the first and second contact elements (6; 3). The first and second contact elements have respective first and second regions (6; 3) facing each other, and said thermally activatable means (45) is mechanically linked to the first contact element (6).
