Vivid imagery . . . thanks for the trip!I do not know about scrap.

Will post some pictures from the inside when I have them..
Ferrous material such as a nickel-iron alloy, ferrous reeds. They work by using magnets.I bought some, don't know yet exactly how much, between 20 and 25, will make some pictures from inside later, I took 1 keyboard apart and found these "switches" in each key, look like Reed relay, anyone know what's inside, looks like silver or palladium. The glastube is 1,5 cm long
Base metal is some feromagnetic alloy, but contacts are often plated. If it is silver/palladium or rhodium, I cannot tell from the picture.I bought some, don't know yet exactly how much, between 20 and 25, will make some pictures from inside later, I took 1 keyboard apart and found these "switches" in each key, look like Reed relay, anyone know what's inside, looks like silver or palladium.
