The above is not always the case: I have two phones with electronic ringers. One, a Radio Shack (ET-100, I think; discontinued model), included a schematic that clearly showed that the OFF position of the ring loudness switch electrically disconnected the ringer circuit. The other, an AT&T Trimline 210, causes the other phones in the house to ring more loudly when its switch is set to OFF; so one would guess that it absorbs no ring power when set OFF. David Carter
