elektrilülitid

Elektrilülitid are devices used to control the flow of electricity in a circuit. They act as a gate, either allowing current to pass through or interrupting it. The most basic type is the manual switch, which requires human intervention to change its state. This can range from simple toggle switches found in homes to more complex rotary switches used in industrial settings. When a manual switch is in the "on" position, a conductive path is completed, and electricity flows. In the "off" position, this path is broken, and the flow of electricity stops.

Beyond manual operation, there are automatic elektrilülitid that respond to changes in the electrical system or environmental conditions. These include circuit breakers, which are designed to interrupt the circuit in case of an overload or short circuit, protecting the wiring and connected devices from damage. Fuses also serve a similar protective function, using a thin wire that melts and breaks the circuit when excessive current flows. Relays are another type of automatic switch, often used to control larger currents with a smaller control signal. The design and application of elektrilülitid are diverse, catering to a wide array of electrical needs and safety requirements.
