What does interruptor mean?
An interruptor is a rare noun meaning someone or something that interrupts. Its most straightforward sense is a person who intrudes on speech or conversation, though the word can also refer to a device that interrupts an electrical circuit. The form is unusual today: “interrupter” is the standard spelling in most modern English. Nevertheless, “interruptor” has appeared in formal, older, and technical contexts, often giving the idea of interruption a more formal or mechanical quality. In conversation, using it for a person may sound deliberately old-fashioned, while the technical sense belongs mainly to specialized or historical descriptions of electrical equipment. The word is consequently more noticeable than a completely ordinary noun, and writers normally choose the familiar “interrupter” unless the older spelling has a specific stylistic or historical purpose.

Where does interruptor come from?
The word belongs to the Latin-derived vocabulary of interruption, based on the Latin prefix inter-, meaning “between” or “among,” and the root rumpere, meaning “to break.” Its formation parallels the more familiar English noun “interrupter,” with “-or” indicating an agent or instrument. The spelling is an older variant that survives in some British and specialized usage, whereas “interrupter” became the usual modern form.
