The Specs Switch is the smallest switch in the Ablenet family. It measures 1-3/8″ in diameter and takes 3 ounces of pressure to activate. Each Specs switch package comes with three bases: one flush base (use when you want to use a cluster of switches), one flange base (to mount switch to almost any surface or use with mounting system), one strap-adaptable base (mount around objects like headrests or armrests). A 24″ strap to use with the strap-adaptable base ia also included with the switch. It comes in a variety of colors.
