lülititele

Lülititele, often translated as "switches," are fundamental components in electrical systems used to control the flow of electric current. They act as a gate, allowing or preventing the passage of electricity to a device or circuit. The most basic type is a manual switch, which requires physical interaction to change its state, such as a toggle switch, push button, or rocker switch. These are commonly found in homes for lighting and appliances, and in various electronic devices.

Beyond manual operation, switches can also be automated. These include relays, which use an electromagnet to operate a switch remotely, and sensors that trigger a switch based on environmental changes like light, temperature, or motion. Solid-state switches, such as transistors and thyristors, are electronic components that control current flow without moving parts, offering faster switching speeds and greater durability, making them essential in modern electronics and power control applications. The choice of switch depends on the specific application's requirements for current handling, voltage, switching speed, environmental conditions, and method of activation.
