Here’s something new (for some of us at least). I’ve been struggling with faulty hall wiring for some time since another room rewire – well, not faulty, more disconnected. The problem is while I can easily seal up the original wiring with just one hole in the (flat roof) ceiling and acquire new power from elsewhere, the two interlocking wall switches are another matter – they go up inside stone walls and into the ceiling space at each end of the hall … not a problem but for the flat roof and the fact that I have no idea where the two of them meet up.
I’d really rather not dismantle the entire hall ceiling to find out where the switch wiring meets the power and there is no way to get to the switches or the wiring from above. My choices were boiling down to one – some kind of battery powered remote switches – and how would I do changeover? two circuits?
Well, I trawled through EBay and I have what I believe to be a sensible solution. One small mains powered receiver (not a problem as I have to provide power to the LED ceiling lighting anyway) and two cordless, self-powered (no batteries) switches. And they work spectacularly well. Go to Amazon and pay £30 for the privilege or EBay for £15 the lot as I did (inc. post).
As you can see, SIMPLES, initially hold down the button on the round receiver for 3 seconds – then press each switch for the same amount of time and they are paired. It is that simple (10 seconds on the receiver to forget the switches).
How does this work? Kinetics! Pressing a switch normally produces enough electricity to send a short radio signal – claims for distance with radio kit are usually not worth a light (20-30 metres indoors), so suffice it to say I put the switches at one end of my large office and the receiver at the other end – everything worked completely reliably.
Check out “Wireless Remote Control Kinetic Self-powered No Battery Wall Light Smart Switch” on EBay, they were from the first place I came to. Saved my bacon, that’s all I have for now, more once the install is complete. I hope this gets someone else out of the same jam I was in.
Assuming this works well, I have some shelf lighting to add, I may do the same thing.
