Updating light switches

Second, there is a different kind of hole on the back of some styles of receptacle that will not hold on even to 14 gauge wires; these rely on your tightening the side-screws to hold the wire solidly in those holes. The most common mistake can happen when the old switch had three rather than two black wires connected to it, even though it was a regular " single-pole" (not 3-way) switch.
