1. Nintendo Switch简称NS，是日本任天堂公司出品的电子游戏机，于2017年3月3日在日本、北美、欧洲和中国香港发售；同年12月1日在韩国和中国台湾发售。2022年1月11日，任天堂Switch OLED在中国内地发售。 NS拥有可拆卸控制器和可分离式主机，游戏载体使用了专用卡带，主机处理器使用了英伟达定制的Tegra X1系统芯片，这是任天堂首次采用英伟达的系统芯片。NS自2017年3月上市以来，仅用9个月就卖出超过1400万台，超过WiiU 1350万台的累积总销量。 截至2020年12月31日Switch主机销量7987万台。
2. Switch是交换机，前身是网桥。交换机是使用硬件来完成以网桥使用软件来完成过滤、学习和转发过程的任务。Switch速度比HUB快，这是由于HUB不知道目标地址在何处，发送数据到所有的端口。而Switch中有一张转发表，如果知道目标地址在何处，就把数据发送到指定地点，如果它不知道就发送到所有的端口。这样过滤可以帮助降低整个网络的数据传输量，提高效率。 以switch命名的还有动画以及漫画作品。
