Abstract
A hold-up battery switch includes an exterior cap having an opening and a zeroize circuit board. The zeroize circuit board includes a zeroize contact. The d zeroize contact being located within the opening of the exterior cap. The exterior cap has an exterior cap exterior interface. The exterior cap exterior interface is configured to engage a negative terminal of a hold-up battery.
Claims20
A hold-up battery switch comprising:
- an exterior cap having a planar surface and a cylindrical surface, said planar surface connected to said cylindrical surface, said cylindrical surface and said planar surface forming a volume, said planar surface closing a first end of said volume, said planar surface including a first opening therein, said volume having a second opening at a second end of said volume, said second end being located opposite said planar surface, said first opening in said planar surface being smaller than said second opening;
- and
- a zeroize circuit board located within said volume of said cylindrical surface;
- said zeroize circuit board including a zeroize contact;
- said zeroize contact being located within said first opening of said first planar surface of said exterior cap;
- said cylindrical surface of said exterior cap having an exterior cap exterior interface, said exterior cap exterior interface being configured to engage a chassis of an advanced ground-air networking radio.

A hold-up battery switch comprising:
- an exterior cap having an opening;
- a zeroize circuit board;
- and
- an electrical insulation ring configured to provide electrical insulation between said exterior cap and said zeroize contact;
- said zeroize circuit board including a zeroize contact;
- said zeroize contact being located within said opening of said exterior cap;
- said exterior cap having an exterior cap exterior interface, said exterior cap exterior interface being configured to engage a chassis of an advanced ground-air networking radio;
- said insulation ring is configured to prevent a zeroizing of the advanced ground-air networking radio from being triggered by a grounding to said exterior cap.

An advanced ground-air networking radio system, comprising:
- a power adapter;
- an advanced ground-air networking radio;
- a hold-up battery having a negative terminal;
- and
- a hold-up battery switch, operatively connected between said power adapter and said negative terminal of said hold-up battery;
- said hold-up battery switch including an exterior cap having an opening and a zeroize circuit board;
- said zeroize circuit board including a zeroize contact;
- said zeroize contact being located within said opening of said exterior cap;
- said exterior cap having an exterior cap exterior interface, said exterior cap exterior interface being configured to engage a chassis of the advanced ground-air networking radio;
- said hold-up battery switch being configured such that when said hold-up battery switch is in a non-zeroized state, said hold-up battery switch provides a low first impedance path between said negative terminal of said hold-up battery and a chassis of said advanced ground-air networking radio;
- said hold-up battery switch being configured such that when said hold-up battery switch is in a zeroized state, said hold-up battery switch provides a high second impedance path between said negative terminal of said hold-up battery and the chassis of said advanced ground-air networking radio;
- said first impedance path having a lower impedance than said second impedance path.
