SwitchHopper is an inexpensive switch interface. SwitchHopper provides a
place to plug switches into a computer. There are 3 switch inputs in
SwitchHopper. When you plug a switch(es) into a the SwitchHopper jack(s),
the switch(es) ‘become’ standard mouse-clicks (Win: left, middle, right;
Mac: left, drag, 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!
SwitchHopper does not interfere with the operation of other pointing
devices, such as a mouse. It works in addition to your mouse. Your mouse
retains all of its normal functions.
