Control access should not be impeded by any position of an adjacent control.
Additional Information: Figure 11.4 and Table 11.5 show recommended minimum separation distances for controls. In most cases, control room operations will require greater separation.0700

1 Pushbuttons within an array, 19 cm (0.75 in.) center to center.
2 Legend switches within an array, no minimum distance, but should be separated by a barrier. Barrier should be at least 0.125-in. wide, 0.183-in. high, with rounded edges. Legend switches manufactured as elements of a module or modular array may be mounted as closely as engineering consideration permits.
