Abstract
An electric device is disclosed. In an embodiment, the device includes an electric element having an element terminal and a conductive spring being deflected, the spring being electrically coupled to the element terminal by a fusible joint. The device further includes a switch including a first monitor terminal and a second monitor terminal, the switch having a state that is changeable between a first connection state, where the first monitor terminal and the second monitor terminal are electrically coupled, and a second connection state, where the first monitor terminal and the second monitor terminal are electrically decoupled, and wherein the electrical device is configured such that when the joint fuses, the spring relaxes, thereby decoupling the spring and the element terminal and changing the state of the switch.
