make-before-break
adjectiveElectrical engineering
Of a switch or other electronic device, that creates a new electrical connection before an older one is broken.
Why this one
Connects the new contact before releasing the old. In inductive circuits the sequence matters more than the connection.
In use
That tap changer is make-before-break, so the winding never sees an open circuit while it's shifting taps.
