AI overview
An electrical switch is a device that controls the flow of electric current by opening or closing a circuit, and they come in many different types and sizes depending on their intended use. Switches matter because they allow us to safely turn electrical devices on and off, and to control when electricity flows through our homes, appliances, and equipment.

開關是指一個可以使電路開路、使電流中斷或使其流到其他電路的電子元件。最常見的開關是讓人操作機器裝置或下達命令的手動操作開關，其中有一個或數個電子接點。接點的「閉合」（close）表示電子接點導通，允許電流流過；開關的「開路」（open）表示電子接點不導通形成開路，不允許電流流過。
