How does the circuit ensure that the output contacts are NEVER shorted during changeover ie "break before make" as per a standard toggle switch
Most published ccts dont address this problem properly or the solution is trivial and flawed with potential unreliability. A conventional mechanical spdt toggle switch does nto have this problem and its only likely failure is a welded contact

It doesn't.
MOSWITCH-SPDT is designed to switch two different loads for the same power supply, the two outputs are controlled by MOSFET (AO4805) and the action time is at microsecond level. If connecting both loads to the power supply at microsecond level is unacceptable, then this board should not be used for such use case.
Output-A has higher priority than output-B, because the MOSFET that controls output-B takes output-A as the controlling signal.

exactly as i thought, thnx for your honesty, most others try and bluff this or convolute it with complex logic gates. with Lipo batteries no momentary s/c of contacts is acceptable, large fault current spikes may occur
