How it's used

This term is primarily used in technical, industrial, or electrical contexts to refer to safety mechanisms like circuit breakers, fuses, or guards on machinery. It sounds formal and professional, so it is rarely used to describe personal safety gear like helmets or seatbelts, for which other specific terms are preferred. When discussing household electrical safety, it is often used interchangeably with specific component names.

Common mistake

Do not use this to refer to personal protective equipment like masks or gloves, as those are usually called 保護裝備. Using the wrong term can make you sound like you are talking about a mechanical switch rather than wearable gear.
