ABSTRACT:
A temperature safety device includes an electrically insulative support, electrical connectors extending outwardly of the support, first and second contact elements having first fixed ends connected with the electrical connectors and free ends engageable to provide a switch within the support in series circuit with the electrical connectors. A melt material insert adapted for heat transfer relation with apparatus being protected by the safety device, is included and a mechanical force transfer element is disposed between the insert and the second contact element, applying force thereto to effect closure of the contact elements in part attributable to counter-forces exerted by the contact elements. The device first contact element has a lower directional quantity at its free end than the directional quantity of the second contact element at its free end and the device includes a stop element disposed by the support in confronting relation with the first contact element and coactive therewith upon melting of the insert to limit movement of the first contact element, thereby to enhance opening of the switch and interruption of the series circuit.
