schengen – Does a resident of an EU country need a visa for a short stay in Switzerland?

I am an Egyptian student and I am willing to visit Switzerland for less than 90 days. I have a Portuguese residence permit (because I am a student, I renew every year). In general, I do not have any problems traveling to the countries of the Schengen area. My question is, if I intend to visit Switzerland for less than 90 days, will I need some kind of authorization?
