How it's used

Refers specifically to physical buttons or switches on machines and appliances. It is common to use the verb 撳 before it when describing the action of pushing a button. While it can mean a switch, it is distinct from the more general term 開關 which focuses on the state of being on or off.

Common phrases

Common mistake

Do not confuse this with 掣肘, which is a formal term meaning to be held back or restricted by someone else. Beginners sometimes mistake the latter for a literal physical switch.
