Cordless Switch Interface (dual and single switch versions)
The Cordless Switch Interface for PC & Mac provides a place to plug switch(es) into a computer, without having to connect a cable to a computer. The dual switch version 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 single switch version just has 1 switch input, which can also be 'defined' as just about anything you want.
The Cordless Switch Interface does not interfere with the operation of its own, or other pointing devices, such as a mouse, which retains all of its normal functions (except on the single switch version, you lose the ability to right-click). 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.
