Requirements for Most Digital Timer Switches
Electrical Question: I just bought a Pass & Seymour RT1W Digital Timer switch to replace my simple single-pole switch.
- My problem is that the installation instructions diagram doesn’t match my simple 1975 Constructed home, switch-box configuration which is one wire set – white, black, unshielded ground connected to nothing in the box.
- My New Switch comes with Four Wires:
- White (labeled Neutral)
- Black (labeled HOT, power from circuit box)
- Red (labeled LOAD, power to lamp or fan)
- Green (labeled GROUND)
The ground is easy, but do I connect the other THREE(White, Black, and Red) RT1 switch wires to the TWO (Black & White) I have left in my old switch box?

Thanks for your electrical wiring question Ron.
How to Wire a Timer Switch for Lighting
- Ron, the digital time switch that you have requires a separate neutral wire.
- Your wiring configuration will not work with this timer unless there is a neutral wire in the switch box.
- As described above, the wiring will require four wires for the connections to the time switch.
