TLDR
In this paper, a thermally actuated switch is used to break the electrical circuit through cooperating electrical leads of an electrical system, once a predetermined temperature level is reached by the switch to prevent the possibility of fire and electrical shock in the event of fireexposed leads.Abstract:
A vacuum hose assembly, method of making same, and vacuum cleaner employing same are provided wherein the hose assembly comprises a thermally actuated switch which breaks the electrical circuit through cooperating electrical leads of an electrical system thereof once a predetermined temperature level is reached by the switch to prevent the possibility of fire and electrical shock in the event of fire-exposed leads.read more
