这个必须有上下文才好翻译，中文里的“档”有时候在英文里是不做字面上的对应翻译的，例如：
同时每个开关档也标注了说明，提醒参与者不同电击幅度的危险程度。
The switches were also labeled with terms which reminded the participant of how dangerous the shocks were.
泵的线盒上设计三档调速开关，可按用户不同环境和要求进行调节变速。
Three-speed designed on thetemi terminal box, the user can adjust the speed as the different circumstance and request.
亦可薄膜开关﹑微动开关﹑电脑开关﹑多档开关（须配夹具）等等作点寿命的测试。
It can also test a point's lifetime with membrane switch, jiggling switch, computer switch and multifunction switch which need to be with clamps. |
