Levitation fuse device

An electrical switching device, comprising:

• a housing;
• fixed contacts arranged to be electrically coupled to outside components outside of the housing and to conduct an electrical signal from the outside components to components internal to the housing;
• a movable contact within the housing, the movable contact movable from a first position to a second position, the first position allowing current flow between the fixed contacts and the movable contact, and the second position preventing current flow between the fixed contacts and the movable contact;
• a levitation actuator to cause movement of the movable contact from the first position creating separation between the moveable contact and one of the fixed contacts, the levitation actuator comprising a first bar below the movable contact and a second bar mounted to the movable contact;
• a catch to hold the movable contact in the second position;
• and
• a pyrotechnic device to, upon activation based on the separation, cause the movable contact to move from the first position to the second position.

An electrical system, comprising:

• an electrical circuit;
• and
• an electrical switching device electrically connected to the electrical circuit to open or close the electrical circuit, wherein the electrical switching device comprises:
• at least two fixed contacts,
• a movable contact arranged to operate in a first position and a second position, the movable contact:
• in electrical contact with the at least two fixed contacts in the first position, and
• spaced from the at least two fixed contacts in the second position,
• a levitation actuator mounted on the movable contact or one of the at least two fixed contacts to cause separation between the movable contact and at least one of the at least two fixed contacts when the movable contact is in the first position and a threshold current passes though the at least two fixed contacts and the movable contact,
• a catch to hold the movable contact in the second position, and
• a pyrotechnic device to, upon activation based on the separation, cause the movable contact to move from the first position to the second position.
