Common Contexts
You will often hear "开关" in daily life when talking about lights, machines, or any electrical appliances. It can refer to the physical switch itself or the action of switching on/off.
Collocations and Patterns
- "开关灯" (turn on/off the light): very common in household contexts.
- "开关按钮" (switch button): refers to the button used to operate the switch.
- "开关坏了" (the switch is broken): a frequent phrase when something electrical stops working.
Usage Notes
