Solution with Two Switches In this case you are using two independent
SPST switches. They allow you to get all four combinations from the table
above.

CAN Bus Power Schematics

Each Indu Altimeter has two CAN bus connectors at the back. In the case of
backup battery, only one connector provides backup power to other connected
instruments. The power is limited to 150 mA at 12V (1.8 W).
Typically, Indu Airspeed Indicator is protected with the backup battery from
Indu Altimeter. Connection schematic for such case is shown in Figure 9 on
page 24.

Battery Lifetime

Our backup battery solution was intended to last for the entire lifespan of the
instrument under normal usage conditions. However, there is no guarantee
that it will indeed last that long, and it is possible that the battery may need
to be replaced at some point.
