A customer asked me to look at some top of (kitchen) cabinet up lighting, the old set I believe the step-down died and the last guy took it a way and never came back.
(Absolute monkey, took the fuse carrier out of a FCU and half taped the hole & worktop height)
The thing is the old set has a sensor to switch them on (which if possible they'd like to keep, replacing is a no-go as the cable is trapped) but it is unlike any I have seen before, it has a single 0.75mm core to it and that's it, my guess is it's piezo sound sensor as I can't imagine how else it's powered or how it sends a signal.
Any guesses or ideas would be a great help, the sensor means some sort of relay is required if it wanders into old tech or great expense, I'll swap the FSU to a Switched type and tell the customer that's how it'll have to be.
(although a FSU with a sensor built in would be quite a thing)
Thanks for reading Klaus.
