A DIP switch (Dual In-line Package switch) is a small electronic component used to configure settings on devices. It consists of a series of tiny switches that can be turned on or off, allowing users to customize the operation of hardware like computers, printers, and network devices. Each switch corresponds to a specific function, such as enabling or disabling features. DIP switches are typically mounted on circuit boards and are easy to use. By flipping the switches, users can change settings without needing complex software. This makes them a practical choice for simple configurations in various electronic applications.
