How it's used

While 鈕 specifically refers to the physical button on clothing, it is also widely used for mechanical buttons or switches on electronic devices. When referring to the act of fastening buttons, the verb 扣 is commonly paired with it. It is distinct from 掣, which is used almost exclusively for electrical switches or buttons on machines.

Common mistake

Learners often confuse 鈕 with 掣. Use 鈕 for clothing buttons or small push-buttons, but use 掣 for light switches, elevator buttons, or power buttons on appliances.
