I prefer Don's definition since that is how we define it here at Xerox.
It always implies a switch or sensor, not merely a mechanical
connection. Besides, if it did not imply some form of sensor then how
would we detect it to produce an alert?

I prefer Gail's definition for interlock. Don's definition implies that
something dangerous to a person or the printer can happen and I don't think
that's always the case.

This one sounds good to me.

I would define an interlock as:

A switch or sensor used to stop operation of the device due to the
opening of a door, cover or other component of the device in order
to prevent injury to a human or improper operation of the device.
