Abstract

L'invention concerne les rupteurs thermiques. Elle se rapporte à un rupteur thermique dans lequel un contacteur 23 comporte plusieurs contacts en saillie repoussés contre une électrode 10a lorsqu'un élément thermosensible 12 est à l'état solide, les contacts s'écartant de l'électrode 10b sous l'action de la propre élasticité du contacteur 23 lorsque l'élément thermosensible 12 a fondu et diminue de volume. Application à la protection des appareils domestiques électriques.
