I don't know how their switches worked, but the Wang 2200 terminals¹ that my father worked with had an interesting angle on tactile feedback; on each keypress a single chunky solenoid attached to it physically moved to give a satisfying "chunk" noise and vibration.

The idea presumably was to give solid mechanical feedback to professional typists used to the same from electromechanical typewriters throwing the type arm onto the platten.

Note this was late 70s/early 80s so I may be confusing/conflating it with other machines.

I can't say for sure about the Wang terminal keyboards, but what you're describing sounds a lot like a mechanism from some IBM Model B keyboards (usually called Beamsprings). I have an IBM 5251 keyboard that has a solenoid that hammers the side of the metal case whenever you type, and I've heard that it was added as users would have been used to typewriters and wanted to know for sure when they had registered a keypress

This guy sells new beam-spring keyboards with optional solenoids. https://www.modelfkeyboards.com

I have never seen one in person.
