I agree, there's a significant distinction between "the switches were (physically) flipped" and "the circuit was opened/closed".
In this case, it may be a moot distinction, particularly if no physical evidence of fault or tampering has been discovered in investigation. But, in theory, very important - there's a lot of potential grey-area between the two statements.
The proximity of the incident to the ground may also increase the possible attack vectors for simple remote triggers.
My understanding from what we've been reading is that these are physical switches that cannot be moved using remote triggers. Wildly speculating, there _may_ be a possibility that the _effect_ of the switch may be triggered remotely, if it's a signal being read by a control unit or computer of some sort that then actuates the specific electromechanical components. But it would seem impossible to move a physical switch to do it.
As an analogy, if you have a smart lock, you can remotely trigger the _effect_ of turning the key using (let's say a bluetooth control), but if a key is inserted into the keyhole, unless there is two-way mechanical linkage, that key _will not turn_.
Any switch becomes irrelevant if a saboteur has access to the behind-the-panel wires that the switch operates.
But I presume that would leave physical evidence which would have been discovered by now. Presume, but cannot be certain.
