Please follow the instructions there.

If you need to lock the screen when you leave it... Just log out and you will need a password to log into again.

the thing is that when you press lock screen, another user can still press switch user to change accounts so they can still use my mac. is their a way i can stop this?

The best way I found is to make a hot corner to start the screen saver. Then, you don't have to log off and stop all your services. You just come back and click the screen, enter your credentials, and... BOOM! that's it.
