What Is This?

Hi, in going through the e-waste load I've come across a bag of these. Does anyone have any idea what they are? The metal tags are slightly magnetic. The transparent plastic is sticky.

Thanks for any input!

I'm assuming its some kind of button pad. I've seen those square looking things when I've torn down e-waste but I can't remember where exactly. I know they flex when you push them so that's why I'm saying they are some kind of button setup. Maybe someone else will have a more definitive answer.

yup thats what they are. the grey looking stuff is silver.
