The C&K Components BD04E is a standard profile DIP switch, offering a traditional full profile and extended actuator for ease of use. Its open bottom construction allows for solder washing without tape sealing, making it suitable for various cleaning methods. Common applications include address switching in industrial controls, logic switching in computers and peripherals, and function controlling in numerous applications. The switch is constructed with glass-filled polyester (PBT) for the case and cover, glass-filled nylon 6/6 for the actuator, and phosphor bronze contacts with a tin-lead alloy over nickel plate for the terminals. It is designed for both hand and machine soldering and is available in full-tube quantities.
