Back when Ruby stood with Oobleck and saw those Goliaths, Crescent Rose shifted on her desire to kill them, Jaune's Crocea Mors shifted from shield to sheath when he wanted to show Ruby it could. The weapons are intuitive to its owner's desires, motivated by their aura to function accordingly. I've kind of been assumed 2 things:

weapons changing form used a switch, Juanes Shield has a button as Cardin used it and Weiss uses her hand to change dust chambers (Pyrrha may be an exception).

Weapons being fired requires aura use, Weiss's Martynester doesn't have a trigger and nor do Russell's daggers, Yangs gauntlets don't have triggers.
