What is the proper term for the upper part, the one we push on push button switches? Is it button or knob (I also saw it referred as head and actuator)? I am asking because I want to buy some for a project but I don't want the whole mechanism for the contact to be made, just the plastic upper part. Red part in this picture.

It's called a button. Button is something you push, knob is something you twist, in general.
