Understanding the Wiring Setup

Hardwiring LED strip lights to a wall switch requires a clear understanding of the electrical circuit and wiring connections involved. The basic setup involves integrating the LED strip’s power supply with the switched power line controlled by the wall switch.

Key points to consider:

  • The wall switch interrupts the hot (live) wire to control power flow.
  • The neutral wire remains continuous, providing a return path for current.
  • The LED strip’s power supply will be connected downstream of the switch to ensure it only receives power when the switch is ON.
  • Ground wires should be properly connected for safety compliance.
  • Confirm the power supply voltage matches the LED strip specifications to avoid damage.

Step-by-Step Wiring Procedure

Follow these steps carefully to hardwire LED strip lights to your wall switch:

  • Turn off the power at the circuit breaker to prevent electrical shock.
  • Remove the existing wall switch cover and switch, exposing the wiring.
  • Use a voltage tester to confirm power is off at the switch terminals.
  • Identify the line (hot) wire, load wire, neutral wire, and ground wire.
  • Connect the line (hot) wire from the power source to one terminal of the wall switch.
  • Connect the load wire from the other switch terminal to the positive input of the LED strip power supply.
  • Join the neutral wire from the power source directly to the neutral input of the LED strip power supply.
  • Connect the ground wire to the switch’s grounding screw and the LED power supply ground terminal.
  • Secure all wire connections with wire nuts and wrap them with electrical tape for added safety.
  • Mount the switch back into the electrical box and attach the faceplate.
  • Connect the LED strip light to its power supply following manufacturer instructions.
  • Restore power at the breaker and test the switch to verify proper operation.

Electrical Safety and Preparation:

Before starting any electrical work, turn off the circuit breaker that controls the lighting circuit to prevent electrical shock. Use a voltage tester to confirm that the power is off at the switch location and wiring points.

Identify the power source feeding the circuit. The LED strip power supply will need to be connected to a switched power line, so the wall switch can control the on/off function effectively.

Wiring Configuration for Hardwiring LED Strip Lights to a Wall Switch

The key to controlling LED strip lights with a wall switch is wiring the power supply to the switch so it receives power only when the switch is in the ON position. The LED strip itself connects to the power supply output.

Component Wire Color Function Connection Point
Power Source (Line) Black (hot) Supplies live voltage Input terminal of wall switch
Wall Switch Output Black or switched hot Delivers power when switch ON Input terminal of LED power supply
Neutral White Completes circuit Neutral terminal of LED power supply and neutral wire from power source
Ground Green or bare copper Safety grounding Ground terminals and grounding conductor
LED Strip Positive Red or marked (+) Positive DC output from power supply LED strip positive input
LED Strip Negative Black or marked (-) Negative DC output from power supply LED strip negative input

Step-by-Step Wiring Process

Step 1: Turn Off Power

Switch off the circuit breaker controlling the lighting circuit. Verify power is off using a voltage tester.

Step 2: Prepare the Wall Switch Wiring

  • Remove the existing switch (if any) and disconnect wires.
  • Identify the line (hot) wire feeding the switch box.
  • Strip about ¾ inch of insulation from each wire end.

Step 3: Connect Line Wire to Switch

  • Connect the incoming black (hot) wire from the power source to one terminal on the switch.
  • Connect a black wire from the other switch terminal to the input (line) terminal of the LED power supply.

Step 4: Connect Neutral and Ground Wires

  • Join the white neutral wire from the power source to the neutral terminal on the LED power supply.
  • Connect the ground wire(s) to the switch grounding terminal and power supply ground.

Step 5: Connect the LED Strip Lights

  • Connect the positive (+) output terminal of the LED power supply to the positive input on the LED strip.
  • Connect the negative (-) output terminal of the power supply to the LED strip’s negative input.

Step 6: Secure All Connections and Mount Components

  • Use wire nuts or push-in connectors to secure wire splices.
  • Wrap connections with electrical tape for added safety.
  • Mount the switch back into the wall box and secure the LED strip lights along the desired surface.

Step 7: Restore Power and Test

Turn the circuit breaker back on and test the wall switch. The LED strip lights should turn on and off in response to the switch position.
