IPA: /ɪnˈrʌptər/
KK: /ɪnˈtɜːrʌptər/
A device that automatically opens and closes an electric circuit, often used to control the flow of electricity.
The interrupter in the circuit helps to manage the electrical flow safely.
Interrupter → It is formed from "inter-" (meaning between) and "rumpere" (meaning to break). The word describes someone or something that breaks in between a flow or conversation.
Picture someone who 'breaks in between' ('inter-') a discussion — that's why an interrupter is someone who interrupts.
