A fail-safe assembly for an electronic or electrical component, device, system or apparatus with coacting operatively associated contacts has an impact member, normally maintained in a stressed and disengaged portion, and a meltable or fusible member for holding and for actuating the release of the impact member to guard against the danger of fire and damage due to current overload and/or unacceptable increases in the temperature in the current-carrying members for operating the coacting contacts or the ambient temperature for any reason and assures, on melting of the meltable or fusible member, that there are sufficient forces created to open and maintain the coacting contacts in the open position.
