Spiffy99 explains,

The MCAS can be turned off completely, but pilots need to recognize the issue and know where the switches are. Apparently on normal 737s the autopilot turns off when a pilot manually overrides its actions. MCAS does not turn off unless you actually throw its "off" switch.


My understanding is that three switches must be thrown (in different places around the cockpit) to completely disable the MCAS, all while putting 80 KG of force on the control yoke to counteract the system as the aircraft bucks and pitches, often close to the ground.

I'm surprised more B737 Max's haven't been lost.
