My wife and I recently moved into a new home. There is a room which we understand the former owner used as a private doctor's practice. As such in one corner of the room, there is some telecoms equipment for a business/commercial digital telephone line. Near to this equipment, there is a switch on the wall for which we cannot determine the function.
I am intending to remove the telephone equipment from the wall, as we will be redecorating the room. However, I'd also like to remove the switch, but unsure how to determine what it does. If you switch it on, a red light on the switch comes on which indicates there is power there, but what it is switching on isn't clear. Can't see anything happening when I turn switch on other than this red light built into the switch itself.
It proximity to the telephone equipment makes me wonder if it's related, but it is also just far enough away that it is conceivable that it might not be anything to do with that.
Is there any way of determining what the switch does? Perhaps a way of tracing the wires in the wall to see where they go?
Additionally, if we determine the switch can be safely removed, with what would we fill in the hole left behind?
