"Removing wires from the 'clutches' of our users is always a challenge. The solution, of course, is to reduce the number of wires!" RJ
The Cordless Switch Interface for PC & Mac provides a place to plug switches into a computer, without having to connect a cable to a computer. It has 2 switch inputs. When you plug a switch into one of its 2 jacks, the switch(es) ‘become’ standard mouse-clicks (Win: left, right; Mac: left, control-click), and with installation of the accompanying software, you can configure each button to 'be' any mouse-button event or keystroke you’d like!
The Cordless Switch Interface does not interfere with the operation of other pointing devices, such as a mouse, which retains all of its normal functions. Some people get these to be able to control a cursor on a large screen and move a switch around the room, away from the computer.
