There are a number of USB switch connectors available from different manufacturers, and not all work in the same way. This article should help you to identify the switch connector you need. Does it matter how it works?When you plug a USB device into Windows the USB device tells Windows what it is - keyboard, digital camera, joystick or whatever. Windows can then find the driver and install the device. A switch is not a recognised Windows USB device, and registering a new device is expensive, time consuming and a hassle for the users (who need to install extra drivers). Instead, the USB switch connectors that are available act as a keyboard or a joystick. This is important, because you must be sure that the software you are using supports the device the switch connector is emulating (keyboard or joystick). If it does not then check to see if the switch connector comes with software to make it compatible. Keyboard switches | Joystick switches | | Pros: Supported by a wide range of software. | Pros: Can be used to play games that are not designed for disability. Supported by major switch software (Clicker by Crick, The Grid and WordWall by Sensory Software and Writing With Symbols by Widgit). | Cons: May type into any Windows program, which might cause problems. | Cons: Not all disability software supports joystick input (but provided software will help). |
