Rotary kytkimet, also known as rotary switches, are electrical switches that allow the connection of one common terminal to one of several output terminals. They are commonly used in various applications where multiple connections are required, such as in telephony, automotive systems, and industrial machinery. Rotary switches are typically operated by a rotating shaft or knob, which mechanically moves the contacts to different positions.

The basic structure of a rotary switch includes a central shaft, a set of contacts, and a mechanism to rotate the shaft. The contacts are arranged in a circular pattern around the shaft, with each contact corresponding to a specific position. When the shaft is rotated, the contacts move to a new position, establishing a connection between the common terminal and the selected output terminal.

Rotary switches can be classified based on the number of positions they have. For example, a 10-position rotary switch has 10 contacts, allowing for 10 different connections. They can also be classified based on the type of contacts used, such as spring-loaded contacts or mercury-wetted contacts.

Rotary switches are valued for their simplicity, reliability, and ability to handle multiple connections. However, they can be more complex to manufacture and maintain compared to other types of switches. Proper care and maintenance are essential to ensure the longevity and reliable operation of rotary switches.
