Abstract
A signaling device adapted to be electrically coupled to an electric potential applied to terminals of a fuse element or to clips of a fuse holder. The signaling device is adapted to signal to the outside at least one property of the fuse element. In addition, the signaling device includes at least one transmission layer having an electrically controllable transmission factor.
Claims16
A signaling device configured to be electrically coupled to an electric potential applied to terminals of a fuse element or to clips of a fuse holder, wherein said signaling device is configured to signal to outside of the signaling device at least one property of said fuse element,
- wherein said signaling device comprises:
- at least one transmission layer having an electrically controllable transmission factor;
- a transparent rigid top cover positioned apart from the transmission layer and covering the transmission layer;
- and
- a substrate provided with electrical terminals being electrically connected with terminals of the transmission layer, and being connectable with the terminals of the fuse element or the clips of the fuse holder;
- and
- wherein the signaling device comprises a suppressor diode connected in parallel to the transmission layer, and further comprises at least one capacitor connected in series to the transmission layer and the suppressor diode.
