[Q] Broken Power Switch

Greetings.

Today the power switch from my Note stopped working.
I found a website that will replace it for an original Samsung one, but I would like to ask if anyone has a better alternative here on the US.
This is the one I got:

Also, it is weird that now that the power button doesn't work at all, I have to take out the battery to "turn off" the phone. But when I put the battery back on, the phone turns itself on. Is that normal behavior?

Thank you in advance.
