Use switch as button (alien.top)

Hi! So, the power button on my case isn't working properly, and I wanted to try to replace it. I accidentally bought some capacitative switches instead of buttons, and I'm wondering if I can do anything with them to make them work.

Thank you!

I have no idea how these work from pictures alone. Do you have a manual or whitepaper with them to explain how they work?

They are designed to drive relays, so it's not going to be a case of just hooking them up directly to your motherboard.

Might be easier for now to just get some momentary switches until you can do further reading on how those capacitive pads work, how to integrate them with relays, and how you can get those relays to operate as motherboard switches.
