摘要： Systems and methods directed to a visual safe indicator (VSI) for mechanical interruption of power to a fuze are provided. A VSI includes a circuit board including 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, or any combination thereof. 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 engages the pair of spring contacts with the pair of contact pads to complete a circuit through the VSI. The disconnected position disengages the pair of spring contacts from the pair of contact pads to open the circuit. Additional systems and related methods are also provided.
