No it does not. Switches and other devices may act upon such signals in any way possible, e.g. being broken after attaching such a tester. That is one reason why I recommended to use the active part of the tester on the side where the switch would be connected: It forces you to unplug the cable from the switch and plug it into the tester. -- Regards, Kai Replies to list-only preferred.
