GUMS-
(From several resources I have saved)
There is no 'feedback' to the pilot from the stick besides its physical position, its totally fly by wire and sitck deflections are monitored by microswitches, probably feels much like a standard computer joystick prehaps.
The Rotational Hand Controller (RHC) is an analog controller, not digital, so it uses potentiometers, not microswitches, to measure stick deflection. (Technically, there are microswitches in it but they are used for BFS engage, trim, PTT, etc, not flying). Like a PC joystick, the RHC has centering springs that provide increasing resistance to larger deflections: 1.45 in-lb per deg in pitch, 2.1 in-lb per degree in roll, and 0.7 in-lb per degree in yaw.
