Got a replacement set of touch switches for my DAC to replace the one that broke. But it looks like i need to remove some glue before replacing the switches and i have no idea whatsover how to do this except maybe with a hair dryer to loosen up the glue a bit.....I am nowhere near being a DIY!!:redface:

See pics of the replacement part and the glued in part it will be replacing, hopefully....

    I can't make out heads or tails from those pics.
    First pic looks like a dash out of a '53 Nash Rambler.:lol:

    No idea as to glue type?
    Does it look like hot glue, I can't tell from the pics.

    Try a Q-tip with some alcohol, soak around the "glue" mounting points, may have to apply it more than once.

    You can try freezing the part first and then try and remove it. Try a thin blade screwdriver or sharp thin scraper to pry the parts apart. Just remember too much force and you can deform the face plate. Sometimes a razor blade works well to get between the parts but use one of them razor scrapers; if you push a single edged blade with your fingers and slip/blade flips, you're gonna bleed and need the hospital.

    EDIT: You can do a search and find more details about the freezer method.

    Heat and/or cold are both excellent suggestions. Go easy with the first; with the second (and I am not kidding!) colder is better... do you have access to dry ice pellets? Liquid nitrogen?

    Next place to go if neither approach works out would be solvents... Ethanol is probably too polar; acetone is next on the lise; xylene (the principal component of "Goof-Off" paint splatter remover) would probably be my next choice, followed by toluene then we get into naptha/lighter fluid... (from more polar to less polar; just like organic chemistry class!).

    would Methyl Ethel Ketone be too aggresive I have used it to remove glue on speaker baskets and corrosion on PCB boards.

    MEK will dissolve some plastic. I wouldn't use it.

Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same.

    Pretty similar to acetone (which is dimethyl ketone); as noted above it will attack some plastics, so proceed with extreme care if any sort of plastic is involved.

    Starting with chilling or heat is really an excellent and pretty safe place to start!

    The freezer would be my first choice, with light heat if that doesn't work; and either method might need a little help from the above mentioned small screwdriver or flat blade.

    Will try the freezer way first as the button assembly is all plastic and with peripheral neuropathy in both hands and fingers using a straight blade is iffy at best :eek:

    You may have to try dry ice if the freezer doesn't work.

    Hey Hey Hey! Got lucky for a change and was able to use a small flat-head screwdriver :) Now i have to go out and buy some super-glue as we don't seem to have any around the house and I don't think Elmer's would work that well :mrgreen:

    Thanks for everyone's help!
