An electrical switch is a device used to control the flow of electricity in a circuit by turning it on or off. It acts as a bridge, allowing or interrupting the current to operate electrical devices such as lights, fans, and appliances. Switches come in various types, including toggle, push-button, rotary, rocker, and smart switches, each suited to different applications. Electrical switches are designed to provide safe and reliable operation. They are made from durable materials like plastic and metal, with insulated components to prevent electrical hazards. Modern switches often feature sleek designs and advanced functionalities, such as dimming, motion sensing, or remote control via smartphones. Used in homes, industries, and commercial spaces, switches play a vital role in electrical systems. Their ease of use, efficiency, and integration with smart technologies make them indispensable for managing electrical circuits and ensuring user convenience and safety.
