If you take apart an L22 you will find an internal strapper (ie a connecting wire) soldered into place that connects the two live terminals. This allows you to have a single live feed powering two different switched live loads.
I have a suspicion that sometimes this strapper confuses the processors in the switch. I’m tempted to “experiment” – in other words potentially burn £100 – by cutting the internal strapper and find out of the switch still works, or works differently.
Anyone tried this already?
Did you do this? The internal strapped is causing me a bit of grief as I am looking to control two sets of lights on different rings and this is resulting in a borrowed neutral issue as the strapped ends up linking the two rings.
I’m trying to figure out exactly how the internal workings work. Wondering if there is a way I can potentially power the dimmer using one ring and then essentially use the other gang as a remote switch (by not hooking anything up to the other switched live out).
Yes, but I haven’t used it yet. It was a spare so I thought I’d play around.
However I’m finding the L22s to be a bit fragile – having just replaced a blown one today another one elsewhere in the house blew this evening. So I may try the strapperless spare later this week.
This has actually worried me so ive joined up to ask
I installed some lightwave stuff at the weekend, with an L22 switch
I actually put my own wire in between the two live terminals (as thats how it was on the manual switch) – both loads will be on the same circuit.
Is this going to cause a problem?
It shouldn’t, but try removing your strapper and see if it still works. If it does, I’d ditch it and let the switch do the job.
