Happening or existing for a very short time only.
用法模式：
a momentary [noun]
常见错误：
Learners sometimes confuse "momentary" with "momentous". "Momentary" means lasting for a very short time, while "momentous" means very important or significant. For example, "a momentary problem" is a short, brief problem, but "a momentous decision" is a very important decision.

working only while pressed
Used about a button or switch that works only when you keep your finger on it and stops when you let go.
用法模式：
a momentary [switch/button/contact]

近义词
non-latching (Technical term emphasizing that the switch does not stay in the on position after being pressed.)
|
spring-loaded (Describes a similar mechanism that returns to its original position, though not all spring-loaded switches are strictly momentary.)
反义词
