interruttore
switch
Origin: From interrompere (to interrupt) + -tore (agent suffix), from Latin interrumpere.
Also means
circuit breaker
Usage Note
Interruttore refers to an electrical switch or, in a more technical context, a circuit breaker. It is different from pulsante (a push-button) — an interruttore toggles (on/off), while a pulsante is momentary. The feminine agent would be interruttrice, though the device itself is always masculine. Plural: interruttori.
Examples
"Accendi la luce con l'interruttore vicino alla porta."

Turn on the light with the switch near the door.
Literal Translation
Turn-on the light with the-switch near to-the door.
