As an electrician, how often do you get jobs from homeowners to add a 2nd light switch into an existing lighting circuit?

Having recently re-wired my entire home I know how difficult this job can be, particularly if the house has masonry walls and the floor boards are difficult to pull up….this can be a time consuming and messy job.

What if there was an easier way?

I have developed a connected light switch which I know makes this job easier and quicker for the electrician as I’ve used it myself in my own home and if you used it potentially you can charge the customer less per job or make more profit per job or do more jobs in the same timeframe.

In it’s simplest form the system uses two products, the connected switch and the wireless switch.
  1. The connected switch is a replacement device which is installed in place of the existing mechanical wall switch, in standalone operation this does exactly the same job as the existing mechanical wall switch.
  2. The wireless switch is a surface mounted repeater switch which acts as the 2nd light switch.

Installation is as simple as removing the existing mechanical wall switch, installing the new connected switch in its place and sticking the wireless switch to the wall in the homeowners preferred location. The wireless switch can be screwed to the wall or stuck to the wall using double sided adhesive tape. You can even stick the remote switch on a piece of furniture or window if you wanted to. Installation should take no more than 10 minutes. The really neat part to this is that the smart switch uses energy harvesting technology which means that the remote switch is wire-less and battery-less so you don’t need wires for it to work and it’ll never need a battery to be changed.

I designed it to work with UK wiring installations so it doesn’t need a neutral to work, it draws its power through the unswitched and switched live conductors only, it fits into 25mm back boxes and can turn ON/OFF any type of light and DIM dimmable lamps. Aside from this it is able to be connected to the internet so if you have Alexa you can ask her to turn on your lights, do it through an app or automate your lights to turn on & off as you wish.

You can use it as a simple way for wiring up 2-way circuits, it works great as an all off switch to turn all of the lights off from one location, you could use it to add bedside lighting control, etc.

Say you would charge a homeowner on average ÂŁ150 to install an additional light switch. If you used my product then at an approximate purchase combined price of ÂŁ80 for the connected switch and wireless switch you would have ÂŁ70 profit for a job which should take no longer than 10 minutes and have minimal impact to the homeowner.

So if you have made it this far into my post then thank you. I’m planning on launching my product on Kickstarter in a month or two and the reason I am posting this is to get valuable feedback from potential customers. Is this a product you would actually use? Do you think it would make your job easier?

Please let me know any thoughts you may have.
 
The problem with powering devices like this via the L and SL is that they can cause CFL and led lamps to either flash or glow dimly when they should be off.

That is true and a quirk of how the electronics control the lamps. What are your experiences of this? What are the best/worst performing products? What is the lowest load you have seen without dimming?

I have found that as the lighting load decreases this is when the CFL and LED lamps glow dimly. Most manufacturers recommend a minimum circuit power or the use of a dummy load, my device can control a single 9W no problem without either of these.
 
I'm not intending it to replace electricians and there will be many people not comfortable doing it themselves. I see it more as something which can help you along the way by making your job easier.

Ultimately the device will be CE marked and compliant with UK standards and relevant RF certifications. I am at a pre-launch stage and gearing up for a crowdfunding campaign to help me raise funds to complete all testing and manufacture tooling, etc.

Which specific U.K. Standards and RF certifications?
It's no use just stating that it 'complies with standards' that could mean anything!

What is the failure rate and mean time before failure of the device? What are the failure modes? Does it leave the lights permanently on or off when it fails?
 
Where does this figure of ÂŁ150 come from?

Whilst it might be possible to install the switch in 10minutes the whole job will take longer than that.

Agreed - I am just talking about a like for like comparison on the work activities related to installing a second switch.

ÂŁ150 is the generally at the low end of quotes I got from 8 local electricians who I got round to my house to quote for the job.
 
This is part of the story that differentiates my device.

The wireless switch requires no batteries and is entirely self-powered through harvesting energy from the kinetic motion of pushing the switch. No searching for batteries at 3AM in the morning and its great for the environment!

How much energy is actually generated from pushing the switch? Is it really enough to power wireless transmission?
 
Also I went on a tour of Tamlite last October, they are devoloping pr it could even be out along with lots of other lighting manufacturers a device which you will connect into the back of your switch which means you can just switch the lights on anywhere in your house through your phone. How is your product better than that?

Don't mean to come across as challenging but it's something you should be thinking of?

Thanks for the heads up, I'll look into it.
 
Philips hue ................ as many devices as you want, covers most lamps, controlled from your phone ...........

Good point.

Generally "smart lighting" is achieved through upgrading your bulb, through using a product like Philips Hue, or upgrading your light switch with a product like mine. Due to the in rush currents which are generated using both in the same system is not recommended. Mostly its an either or depending on the nature of the installation.

Products like Philips Hue are great and work really well but their achilles heel is that the wall switch needs to be permanently on. If someone turns it off then power is lost to the bulb and you then lose control. Granted that Philips offer a remote switch but this will be rendered useless if the wall switch is toggled. Most of these type of systems are also app controlled therefore if you have a visitor such as a relative or baby sitter how do they control your lights when you are away from home?

Upgrading the switch on the other hand offers a similar level of control (albeit with no ability to colour change) and also provides a permanent switch that users can turn on/off as they wish. This provides a user interface any one of any age can use.
