Sähkövatkain
Sähkövatkain, also known as an electric switch, is a device used to control the flow of electrical current in a circuit. It is a fundamental component in electrical systems, allowing users to turn electrical devices on or off. The basic principle of operation involves a movable contact that either completes or interrupts the electrical circuit. When the switch is in the "on" position, the contacts are closed, allowing current to flow. Conversely, when the switch is in the "off" position, the contacts are open, stopping the flow of current.
Electric switches come in various types, including toggle switches, rocker switches, and slide switches, each designed
The history of the electric switch dates back to the late 19th century, with significant advancements made
In summary, the electric switch is an essential tool in electrical engineering and everyday life, providing
