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. |

1. An electric device comprising:
an electric element having an element terminal; a conductive spring being deflected, the spring being electrically coupled to the element terminal by a fusible joint; a housing comprising an inner wall, wherein the spring is fixed to the housing so that the spring is deflected, wherein a spring section that is connected to the element terminal moves away from the element terminal when the joint fuses; a switch comprising:
a first monitor terminal;a second monitor terminal; anda third monitor terminal,wherein the switch has 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, andwherein, in the first connection state, the first monitor terminal and the third monitor terminal are electrically decoupled and wherein, in the second connection state, the first monitor terminal and the third monitor terminal are electrically coupled, wherein the electric element is arranged on one side of the inner wall and the spring and the switch are arranged on the other side of the inner wall, 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. |
