R406 provides specific reach ranges, which mainly affects the height of the pushbutton and accessibility from a wheelchair. For a forward reach the pushbutton may be at a maximum height of 4 feet (48 inches) and a minimum height of 1.25 ft (15 inches). No obstructions are allowed beside the pole that someone has to reach over. For reaching from the side or what may be called a parallel approach, the same height restrictions apply. However, the reach can be over an obstruction but no further than 10 inches. Graphics from draft PROWAG illustrating the forward and side reach are on the next two slides.

The minimum height would really not be appropriate for mounting pushbuttons and the MUTCD specifies between 36 inches and 48 inches.
