I've got a system that requires weekly maintenance. The first step is turn off system power. The last step is turn on system power.

We've had a few instances of power being left off after maintenance is completed and then somebody has to go back later to turn it on when somebody realizes it was left off. For me, that's a 90-minute round trip.

So, I was thinking it would be great if I could replace the power switch with a 3-way switch as a toggle so that when the system power is turned off, it would turn on a red light by the exit door to indicate that the system is still off.

Is that possible? And if not, is there some other type of switch that would do what I want?

 

I think I understand your issue. Instead of a 3 way switch at the door why not a WiFi switch to start with. This way if the switch is not turned on prior to existing the building and you have left and one hour from there you can turn it on remotely with your smart phone.

Using a 3 way switch you wouldhave to run a line from the original switch location to another location by the door. A WiFi switch I would think would be an easier solution.

 

Yes that will work. Connect power to the common, the red light one traveller and the device to the other traveller.

 

Thanks for the feedback. Unfortunately a WiFi switch won't work because there is no internet service at the location.

Joed, would you happen to know where I could find a wiring diagram? I've tried to search, but have not been able to find what I am looking for.

 

You won't find a wiring diagram.
At the switch
Connect all the neutrals together.
Connect the incoming power to the common screw.
Connect the two loads one each to the traveller screws.
Flipping the switch will toggle the power between the two travellers. One position light on. Other position device on.

 

Thank you to much!
