Wiring a Sensor Light Circuit With a 4-way Switch

Intro: Wiring a Sensor Light Circuit With a 4-way Switch

“To Sensor or Not to Sensor” that was the question.

Automatic lights are great – when to approach the area, they sense your presence and light it up. Great outside a garage when arriving home late at night.

However, if you want to illuminate the area at other times and don’t want things going black if you aren’t moving about within the sensor range, you have to perform some juggling with the control switch to set the device to Permanent On status.

I wanted a simpler setup. A switch I could use to choose between Sensor Control and Always On status without need to remember they instructions that came with the thing several years earlier. I’ve several different brands and suspect they may all work similarly, but this approach is simple and direct.

There is one issue with this set-up, you cannot turn the power at the device off and would need to switch off the breaker for its circuit if you wanted to work on the sensor device (change it out, etc.) In my application, I have room (new construction0 to add a simple one-way switch so I could shut off power just to the sensor device.

Next project will be to use the Sensor to switch between controlling an outside light and an 'inside' light. The burglars may think they made a sound when an inside light goes on. Since you are already home and don't need to light up the drive . . . anyone showing up is unlikely to have been invited.

I used a 4-way Switch to accomplish this. The diagrams tell the story that took me a while to work out. I suspect there are other applications for this circuit – love to see how you configured yours!

Step 1: Here's the Circuit Diagram!

I think it speaks for itself. If not, leave a question and I'll respond and add the necessary detail(s) you discoverd I'd forgot! Thanks for viewing!

    Hello there! We're glad you want to share something with the
    Instructables community! And we’re here to help you out. Due to some recent
    changes on the site, we are no longer able to publish stand-alone videos and
    other forms of incomplete posts. In order to be published live on the site,
    Instructables must consist of the following things:

    - Multiple steps
    showing how you made your project

    - Written
    instructions in each step

    - Your own original

    Beyond making your Instructable simply publishable, this
    guide (https://www.instructables.com/id/How-to-Create-a-Feature-Worthy-Instructable/)
    explains what is required to have your Instructables featured by our site
    editors. It’s very helpful, and definitely worth checking out. We would love to
    review your project again after you have made the necessary edits, and we will
    publish your project if it is eligible. If you have any questions, please feel
    free to ask right here or send us an email at service@instructables.com.
