What is a dip switch?

A dip switch is a small switch used in electronics that is typically used to change settings or select options. They are commonly found on circuit boards and other electronic devices and are often used for setting up things like addresses, configurations, or modes.

Dip switches usually consist of a row of small, individual switches that can be flipped on or off. They are called "dip" switches because they are often arranged in a dual inline package (DIP) format, where the switches are lined up in a row.

Dip switches are commonly used in situations where settings need to be easily changed or adjusted, such as in networking devices, industrial control systems, and computer peripherals. They are usually set manually by physically moving the switches into the desired position.

While dip switches are simple and reliable, they are becoming less common in modern electronics due to the rise of digital and software-based methods of changing settings. However, dip switches are still used in certain applications where physical settings are preferred for security or reliability reasons.
