Abstract
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.
Claims8
A bimetallic thermal switch comprising:
- a bimetallic disk;
- first and second electrical contacts;
- a component for electrically connecting and disconnecting the first and second electrical contacts based on movement of the bimetallic element;
- and
- 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,
- wherein the component for electrically connecting and disconnecting the first and second contacts includes a stem being physically separated from the disk when electrically connecting the contacts and being physically connected to the disk when electrically disconnecting the contacts.
