Abstract (en)
[origin: WO2020120057A1] The invention relates to a thermally triggerable indicating or switching device, with a movable, mechanically pretensioned slide, which directly or indirectly triggers or actuates the indicating or switching device, and with a shaped part, which changes its state of aggregation under the effect of heat, wherein the shaped part in the functional state can be arranged in such a way as to block the movable slide. According to the invention, in the initial state the shaped part is loosely confined within a holding space. To bring the shaped part into the functional state, the slide is moved into a position such that a gap opens up between the slide and a slide stop, wherein the shaped part enters the gap and at the same time the slide is pretensioned.
