How to Replace a Stair Light Switch with a Dimmer · Step 4 of 6
In this video
Connect the wires to the new dimmer switch according to your configuration (single-pole or three-way). The two black wires should be connected to the terminals indicated for the main power. The video demonstrates using the quick-connect holes on the new switch; simply push the stripped ends of the black wires into these holes until secure. If your wires are too thick or you prefer, use the screws provided on the side of the switch for connection. Then, take the bare copper grounding wire from the wall box and connect it to the green grounding wire of the dimmer switch using an included yellow wire nut. Twist the wire nut clockwise until it's tight and both wires are securely joined.
