This might deserve clarification from GDC Q&A, but I don't see anywhere that its been said that you have to purchase a switch from the source that markets it as a limit switch.

If Mfgr X sells a limit switch with part # N through multiple marketing channels, and at least one of those channels 'markets' it as a limit switch (or household light switch) and you buy it through another marketing channel, that should be ok.

As a practical matter, anything that it is quite clearly something that 'ought' to be marketed as a limit switch or household light switch will not invite added scrutiny from an inspector. They don't have the time to be asking for documentation on every switch, only questionable ones.

In my point of view, the 'marketed as' requirement allows the issue resolution to go to a neutral third party and tries to avoid long drawn out arguments between an LRI and a team member. It provides a mostly cut and dried resolution path.
