Electrical equipment provided with a visual indicator

Claim 1

AN INDICATOR, FOR AN ELECTRIC DEVICE, WHICH CAN RESPOND TO "OPENING" OF SAID ELECTRIC DEVICE TO PROVIDE A VISUAL INDICATION OF SAID "OPENING" OF SAID ELECTRIC DEVICE AND WHICH COMPRISES: (A) AN ELECTRIC DEVICE, (B) TERMINALS WHICH CAN BE CONNECTED TO SAID ELECTRIC DEVICE AND WHICH ARE NORMALLY IN ONE STATE AND WHICH WILL RESPOND TO AN APPRECIABLE FLOW OF CURRENT THERETHROUGH IN THE PRESENCE OF AN ELECTROLYTE TO ELECTROLYTICALLY CHANGE TO A VISUALLY DIFFERENT STATE TO ENABLE SAID INDICATOR TO SENSE CHANGES IN THE CONDITION OF SAID ELECTRIC DEVICE, AND (C) AN ELECTROLYTE WHICH IS IN ELECTRICALLY-CONDUCTING RELATION WITH SAID TERMINALS AND WHICH WILL RESPOND TO AN APPRECIABLE FLOW OF ELECTRIC CURRENT THROUGH SAID TERMINALS TO CAUSE THE CONFRONTING EDGES OF SAID TERMINALS TO ELECTROLYTICALLY CHANGE FROM SAID ONE STATE TO SAID SECOND STATE, (D) SAID ELECTROLYTE BEING SUBSTANTIALLY INSENSITIVE TO ANY VOLTAGE DIFFERENTIALS BETWEEN SAID TERMINALS AS LONG AS SAID ELECTRIC DEVICE IS CAPABLE OF CONDUCTING CURRENT, THEREBY ENABLING SAID INDICATOR TO HAVE A PREDETERMINED APPEARANCE AS LONG AS SAID ELECTRIC DEVICE IS CAPABLE OF CONDUCTING CURRENT, (E) SAID ELECTROLYTE RESPONDING TOTHE VOLTAGE DIFFERENTIAL BETWEEN SAID TERMINALS, AND TO THE RESULTING APPRECIABLE FLOW OF ELECTRIC CURRENT THROUGH SAID TERMINALS WHEN SAID ELECTRIC DEVICE "OPENS," TO CAUSE THE CONFRONTING EDGES OF SAID TERMINALS TO ELECTROLYTICALLY CHANGE FROM SAID ONE STATE TO SAID SECOND STATE AND THUS MATERIALLY ALTER SAID PREDETERMINED APPEARANCE OF SAID INDICATOR, THEREBY ENABLING SAID INDICATOR TO PROVIDE A VISUAL INDICATION OF THE "OPENING" OF SAID ELECTRIC DEVICE.
