Step 6: Connect Wires to New Switch
Hold the new switch so the “off” position is pointing down. If you are attaching the wires using the mounting screws on the side of the switch, use the tips of stripping pliers or needle nose pliers to gently bend a hook in the wires to fit around the connection screw. Bend the wires in a clockwise direction, so they will be pulled onto the terminals when you tighten up the screws.
Hook each wire around the connection screw, making sure your labels match the old switch, and tighten up the screws to secure the wires to the switch. If you have a ground wire, connect it to the green screw on the switch.
Alternatively, you can insert a straight wire beneath the brass plate next to the screw and tighten the screw to hold it in place, or use push-in connections on the back of the switch if available; but both methods are considered less secure than screw mounting.
