The Smoothie 125 is a low profile, 125mm diameter switch, for the ultimate in comfortable switching. It has a low profile and is angled towrd the user, meaning the operating surface is only 10mm above the desk at its lowest. This switch does not have a flanged base, allowing unrestricted access to the operating surface.  Use who are not able to rest their hand on the switch without operating it may instead rest their hand on the desk in front of the unit and simple "roll" it toward the switch when required.
