TASH Mouse Mover
The USB Mouse Mover allows an individual to control all mouse functions on their computers using a combination of 6 single switches or any multiple switch. The single switches plug into the 1/8" jacks on the front of the Mouse Mover, which plugs directly into the computer, and a multiple switch plugs into the 9 pin jack on the Mouse Mover. Pressing on each switch then delivers a specific mouse function - click, press and hold, release, and all mouse directional movements.
