Step-by-step guide to installing a BOBBIN 2G dimmer light switch, including wiring tips, safety checks, and common mistakes to avoid.

Quick answer

Install the BOBBIN 2G dimmer light switch by first turning off power, then wiring the two dimmer units to your existing circuits, and finally securing the brass plate. Always double-check connections before restoring power.

Why choose a dimmer switch?

A dimmer switch gives you control over the ambiance of a room, from a soft glow to full brightness. The BOBBIN 2G dimmer is designed to be a feature in itself, with a solid brass dial and slim, low-profile plate that complements brass cabinet hardware.

This guide covers the installation of a 2-gang dimmer, which controls two separate lighting circuits from one wall plate. It's ideal for bedrooms and living rooms where you want to set the mood.

Tools and safety first

Before starting, gather a voltage tester, screwdrivers (flathead and Phillips), wire strippers, and a small level. Always turn off the power at the circuit breaker and use the tester to confirm the wires are dead.

If you're not confident working with electrical wiring, hire a licensed electrician. This guide is for reference, not a substitute for professional advice.

Step-by-step installation

Turn off power and verify: Switch off the circuit breaker for the room. Use a voltage tester on the existing switch wires to confirm no power is present. Never skip the voltage test—even if the switch is off, wires could still be live.
Remove the old switch plate: Unscrew the existing wall plate and pull the switch out carefully. Take a photo of the wiring before disconnecting anything. The photo will be your reference when connecting the new dimmer.
Disconnect and identify wires: Loosen the terminal screws and pull the wires off. Identify the live (usually brown or red), neutral (blue or black), and earth (green/yellow) wires. In a 2-gang setup, you'll have two sets of wires. Label each wire with tape to avoid confusion, especially if the colors are similar.
Connect the dimmer units: Follow the wiring diagram included with the BOBBIN dimmer. Typically, connect the live wire to the 'L' terminal, the switched live to the 'L1' terminal, and the neutral to the 'N' terminal. Repeat for the second gang. Ensure all connections are tight. Check that no bare wire is exposed outside the terminal—this prevents short circuits.
Mount the dimmer and plate: Carefully push the dimmer units into the wall box, ensuring wires are not pinched. Screw the dimmer to the box, then attach the brass front plate and tighten the screws evenly. Use a level to ensure the plate is straight before fully tightening.
Restore power and test: Turn the circuit breaker back on. Press the dimmer dial to switch on and rotate to test the range from soft glow to full brightness. Test both gangs. If the dimmer doesn't work or feels hot, turn off power and recheck the wiring.
