ship from Japan This product is a USB cable for self-made input devices that allows you to connect various momentary switches (switches that turn on only when pressed) and perform the operations assigned by the setting software in advance by operating the switches. In addition to keyboard and mouse operations, multimedia keys and gamepad functions can be assigned. The cable can be extended up to 150m. You can also change the length of the cable for each switch. The settings are stored inside the USB connector of the cable, so there is no need to start or resident the software when inputting. It is also possible to connect multiple cables assigned different operations to a computer at the same time and input.
