Outlet / Switch
Removing switch control from an entire existing receptacle (outlet, plug) making the latter live all the time.
Turn off the power. Open up the box containing the switch. Remove the switch from the box. Remove the two non-bare wires from the switch. (If there is a third, bare, wire, remove it from the switch also and put it inside along the side of the box connected to nothing.) Connect the two wires together (1). Close up the box (2).
Refinement (1) If one of the switch wires is short (is a pigtail) and connected to another wire nut, remove it completely. Connect the other switch wire to everything else under that wire nut.
Refinement (2) If you don't have a cover with no hole where the old switch was, put the old switch with nothing connected to it back into the box so the hole is filled.
If only two wires (one white, one black) come into the box with the duplex receptacle, it is not possible using the existing wires to make the bottom receptacle live all the time and the top receptacle stay switch controlled.
If power comes to the receptacle first and another cable goes to the switch further on, then you can do what you want. You will find the white (neutral) of the power feed connected to a silver screw of the receptacle. You will find the black (switched hot) of the switch loop cable connected to a gold screw of the receptacle. The other two wires (probably one white and one black) will be connected to each other with a wire nut and are always hot. You need to bend and snap off the little gold tab between the two gold screws. Connect a short (about 6 inch) black wire between the wire nut (with the existing wires still there) and the other gold screw of the receptacle.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
