Several factors effect the "feel" or perceived speed of the side keys which are
sprung with flat or leaf springs. They are:
1) The position of the leaf spring on the underside of the key relative to the
fulcrum and the point of purchase (pivoting point and the touch part where the
key is touched by the finger).
2) The material of the leaf spring (blued steel, bronze phosphor, gold alloy,
etc.)
3) The dimensions of the spring, its thickness, width and length.
4) The shape or bend of the spring.
5) The bearing points of both the spring end where it makes contact with the
instrument body and the trough or slotted guide along which it slides.
6) The possible addition of lubrication or grease to decrease friction at the
bearing point.
7) The freedom or precision of the pivot point or fulcrum of the key (does it
bind, or hinge freely? Is it free without being sloppy in its fit over the rod
screw and, laterally, between the key posts?)

A qualified repairman can change many of the above to alter the pressure required
to operate the key and affect a speed change.
