[Help] Anyone know the proper name for buttons with the plastic guard on them?

I am looking for a button like this: http://ift.tt/1y1G0Qy

Or trying to build one as a power button for my computer built into my desk face. I am having trouble finding them online (if they exist) and was wondering if there is a proper name for the category.
