Visual safe indicator for interruption of power to fuze systems and methods

A system comprising:

• an unmanned aerial vehicle (UAV);
• and
• a visual safe indicator (VSI) integrated into the UAV, the VSI comprising:
• a circuit board comprising a pair of contact pads,
• a shaft configured to rotate about an axis,
• a visual indicator wheel coupled to rotate with the shaft, and
• a pair of spring contacts coupled to the visual indicator wheel,
• wherein rotation of the shaft rotates the visual indicator wheel to move the pair of spring contacts between connected and disconnected positions associated with powered-on and powered-off states of the VSI, the connected position engaging the pair of spring contacts with the pair of contact pads to complete a circuit through the VSI, the disconnected position disengaging the pair of spring contacts from the pair of contact pads to open the circuit.

A method comprising:

• rotating, by a bistable rotary solenoid of a visual safe indicator (VSI), a shaft and visual indicator wheel to move a pair of spring contacts between connected and disconnected positions associated with powered-on and powered-off states of the VSI, wherein the spring contacts are coupled to the visual indicator wheel;
• engaging, in the connected position, the pair of spring contacts with a pair of contact pads of a circuit board to complete a circuit through the VSI;
• and
• disengaging, in the disconnected position, the pair of spring contacts from the pair of contact pads to open the circuit.
