Thermal fuse containing bimetallic sensing element

摘要

A non-resetable, bimetallic thermal switch. The bimetallic thermal switch includes a bimetallic element, first and second electrical contacts, and a component for electrically connecting and disconnecting the first and second electrical contacts based on movement of the bimetallic element. The switch also includes a non-resetable component configured to disallow electrical reconnection of the first and second electrical contacts after an electrical disconnection has occurred between the first and second electrical contacts.
