Kiertokytkimet

Kiertokytkimet, also known as rotary switches, are electrical switches that allow users to select different circuits or functions by rotating a knob or lever. The internal mechanism typically involves a central spindle connected to a movable contact, which sweeps across a series of stationary contacts arranged in a circular pattern. As the spindle is turned, the movable contact connects to different stationary contacts, thereby directing the electrical current through various pathways.

These switches are commonly used in a wide range of applications where multiple operational modes or selections are required. Examples include selecting different settings on appliances like ovens and washing machines, choosing radio frequencies, or controlling various functions in industrial machinery and automotive dashboards. The simplicity and versatility of kiertokytkimet make them a reliable and cost-effective solution for many switching needs.

Kiertokytkimet can be designed with varying numbers of positions and poles. A pole refers to the number of independent circuits that can be switched simultaneously, while a position indicates the number of distinct electrical connections the switch can make. The construction materials and contact types vary depending on the intended use, with some designed for low-voltage, low-current applications and others engineered for heavy-duty industrial environments. Their robust design often ensures a long operational lifespan.
