DMSD – Compact Configuration. Proven Reliability.

DMSD: Low Profile SMD DIP Switch
The DMSD is a low-profile DIP switch featuring the industry-standard 2.54 mm pitch and
gullwing SMD terminals for reflow soldering. It is designed for address selection, communication
protocol configuration and functional parameter settings in industrial and electronic applications.
The product is available with 1 to 10 and 12 positions and uses SPST contacts. With a height of
3.6 mm, it supports space-efficient PCB layouts. Mechanical life is specified at 2,000 switching
cycles with an operating force of ≤ 8 N. The operating temperature range extends from -40 °C to
+85 °C. Initial contact resistance is ≤ 100 mΩ and remains ≤ 200 mΩ after the specified
reliability tests.
Typical applications include industrial automation, building controls, servers, medical devices,
robotics and consumer appliances. Common use cases are address configuration, RS485 and
Modbus settings, BIOS/CMOS configuration and functional parameter selection. The
standardized form factor and footprint enable straightforward integration into existing hardware
designs.
