The gravitational pull from a one-gram switch ten meters away is around 6 * 10-16 m/s2. That’s around half a neutron diameter per second per second, far below thermal noise, but way above the Planck level.

The switch’s flip does change the fundamental particles of your body and brain. It nudges them by whole neutron diameters away from where they would have otherwise been.
But when you flip the switch, it doesn’t disappear altogether, it just gets displaced by a few millimetres, so the number you care about is this, which is hundreds of times smaller.
