[Star Wars] Can a Jedi/Sith use the force to press the "off button" on an opponent's lightsaber?

Technically, yes, Yoda turned off Ventress' sabers in an early episode of  The Clone Wars.

The real issue is: can they do it in the middle of combat? That answer is probably no - the effort and concentration it takes to locate the switch and flip it while at the same time blocking and avoiding attacks is too much for most.

The Legends novels dealing with Darth Bane added passive shielding to the abilities of trained Force users, which prevents direct telekinetic assault on the user and their weapon. However, that's not an ability shown in any other sources before or since.
