1. A power supply assembly comprising:
a local power source;
a first switch connected to a second switch and the local power source; and
the second switch, configured to connect and disconnect a power supply unit to and from an AC power source in response to a respective control signal,
wherein the second switch is configured to maintain, both: (i) a set state at which the power supply unit is connected to the AC power source and (ii) an unset state at which the power supply unit is disconnected from the AC power source, and wherein maintaining both the set and unset states are without consuming electrical power from any one of the local power source and the AC power source,
wherein the first switch is configured to maintain two states without consuming electrical power from any one of the local power sources and the AC power source, wherein the two states of the first switch are a set state, adapted to switch on the second switch and an unset state.
