I recently bought a 1951 home. There is a switch in the living room that appears to have been intended to control one or more outlets in the room (the switch affects no lights and all lights are controlled by other switches). However, the switch does not affect the outlets either: whether the switch is on or off, all outlets are on.
The outlets are all wired with either two black and two white wires or one white and one black. There are no red wires like you'd see with a typical newer switch-to-outlet configurations. The switch, which is a new replacement, is wired with two black, and the two white are capped off together. The bottom black wire for the switch does receive electricity. But again, no red wire at the switch box.
Other than incorrect wiring, is there a possible explanation in an older home as to why the wires would be configured and would function this way? Is it possible that it is in fact correctly wired to operate outlets but the outlet being controlled would have to be installed a specific way (eg, removing the bridge between the two hot terminals)?
