Also known as: ライトスイッチ
A simple electrical device used to control a light fixture by opening or closing the circuit that powers it. When the switch is on, the circuit is closed and electricity flows, allowing the light to turn on. When the switch is off, the circuit is opened, interrupting the power supply and turning the light off. Light switches are commonly found on walls, near room entrances, and can come in various styles (e.g., toggle, rocker, push-button) to suit different design preferences and functional requirements.
