Robert, I disagree with your premise but I believe your conclusion is
correct. Equipment can have a switch that does not comply as the primary
disconnect as long as it has an acceptable disconnect means such as an
appliance coupler. In that case, the switch provides a user function but not
a safety function within the meaning of the standard.
Any color indicator may be used as long as it is clear that the indicator is
not related to safety. For example, a red activity indicator on a disk drive
is acceptable. However, a red indicator on a power on/off switch may be a
problem even if the switch is not the primary disconnect.

The on/off power switch for a module or system must surely be
considered
to be 'safety related', and therefore subject to the provisions of
IEC73.
What do you do if a customer specifies an integral red neon
indicator in
the switch and certification to 60950?
