The AP-Switch allows you to connect a second, external power supply on a given circuit.

As soon as an external power input is noticed or plugged in, the already existing connection (e.g. to an internal battery) is interrupted.

This makes the AP-Switch to an ideal helper when you require external power e.g. during start-up phase, especially with “kerosene start” of a jet engine, respectively a turbine) or when you implement the AP-Switch as part of an on-board redundancy power supply unit.
