The 5-Switch is a compact USB-based switch control unit which allows users to perform various mouse actions through the use of five external 3.5 MM switches connected to the front of the control unit. The 5-Switch provides a left-click mouse function and allows users to make mouse pointer and cursor movements such as up, down, left and right. The 5-switch is an ideal solution for individuals with limited motor control. It is powered by a USB connection to the computer, so no additional power sources are required. (3.5 mm external switches are sold separately).
