pöördlülid

Pöördlülid, also known as rotary switches, are electrical switches that operate by rotating a shaft or knob to select between different circuits or positions. They are commonly used in applications where multiple functions or settings need to be controlled by a single user interface. The internal mechanism typically involves a series of contacts that are connected or disconnected as the shaft is turned, thereby directing current to different output terminals.

These switches can be found in a wide variety of devices, from simple household appliances like ovens and washing machines to more complex industrial equipment and audio systems. Their versatility allows them to serve purposes such as channel selection on older televisions, mode selection on power tools, or controlling the speed of a fan. The design of a pöördlüliti can vary significantly, from simple two-position toggle-like actions to multi-position rotary selectors with intricate contact arrangements.

The materials used in pöördlülid construction are chosen for their electrical conductivity, durability, and insulation properties. Common contact materials include copper alloys, while the housing is often made of plastic or metal. The lifespan of a pöördlüliti is generally determined by the quality of its construction and the frequency of its operation. They offer a robust and intuitive method for managing multiple electrical pathways in a compact and user-friendly manner.
