ELECOM RS-232C switch, capable of switching between 2 circuits, ideal for data connections. New, unused, but it's an old product and I haven't been able to confirm its operation. I don't know if it works. The box shows signs of aging, such as sun damage. Thank you for your understanding. I will ship it with amateur packaging. I will ship it in its current condition. To prevent issues like product substitution, returns, refunds, and cancellations are not accepted. The shipping method may be changed from Rakuraku Mercari Bin to Yu-Yu Mercari Bin.
