Hi Everyone,
I could do some advice on wiring up a Piezo touch sensitive switch. I'm in the middle of building a desk PC project and thought it would be a nice touch to have a touch sensitive power switch, so I've bought a nice shiny touch sensitive illuminated Piezo switch and can't figure out how it works. The switch I've bought is an APEM PBAR2AFB000LSG found on RS components - http://uk.rs-online.com/web/p/push-button-switches/6919553/
It has 4 wires, two of which are for the bi-colour LED and the other two for the switch itself. I very quickly figured out that it is not quite as simple as wiring the two switch wires to the power switch header on my motherboard. I thought maybe it needed a slightly higher voltage or a tad more current to pass through it to activate so I wired it up in line with the coil in a relay with a 12v supply and when I touch it nothing happens. If I need to power some sort of circuit to get this to work I have the 5v standby power from the PSU and a separate 12v power supply which will provide constant power too so there are a couple of options. I assume I'm going about this in entirely the wrong way so I thought I'd seek some expert advice, any help would be much appreciated.
Cheers
