The 1.27 mm pitch DTCD and DTCJ DIP switches are ultraminiature SMT components designed for high-density electronic applications. With a profile height of just 2.2 mm and up to 46% PCB space savings compared to traditional 2.54 mm solutions, they offer a significant footprint reduction without compromising functionality.
Both variants are available with Gullwing or J-bend terminations and are optimized for automated SMT assembly, which reduces production complexity and costs. The switches support up to 1,000 mechanical cycles and function reliably within a temperature range of -40 °C to +85 °C. Low contact resistance (≤100 mΩ initial) and stable electrical specifications (up to 100 mA @ 50 V) ensure consistent signal performance.
Applications
Typical applications include address setting and configuration in industrial controls, communication systems (such as RS485/Modbus), server hardware (BIOS/CMOS), consumer electronics, and medical equipment. By combining miniaturization, durability, and cost efficiency, the DTCD/DTCJ series offer a scalable solution for modern, compact electronic designs.
