ACCESSwitch
ACCESSwitch is a compact USB adapter that allows the connection of one to two 3.5mm jack switches to a computer or tablet. It makes it possible to control software in scroll mode in a more ergonomic way than traditional wired boxes.
Free of charge, its programming software allows you to set up any keyboard key or mouse action.
Without the software, ACCESSwitch can be programmed from four mini-switches that can be accessed after removal. The emulation of certain keyboard keys is therefore possible on a device other than Windows.
