D3SK Surface Mount Switch is an ultra-small and ultra-thin detection switch that can achieve high-precision motion. Features include a unique contact mechanism that realizes high-precision motion positions and high-reliability contacts; a long stroke that improves ease of use; contact specifications (1a, 1b) and multiple levers that are suitable for a wide range of applications.
The guide describes the D3SK surface‑mount switch, its mechanical layout, contact types, and electrical characteristics. It includes detailed drawings of the printed circuit board footprint, positioning pins, and dimensional tolerances.
Key sections cover contact ratings, operating temperature and humidity ranges, recommended soldering methods, and safety precautions to prevent short circuits or damage during assembly. This manual is written in Japanese.

The D3SK switch measures 3.0 mm × 3.5 mm × 0.9 mm (L × W × H).
The switch can operate from –25 °C up to +83 °C.
Do not use hand soldering; use reflow soldering, limit reflow cycles to two, and allow the part to cool before the next cycle.
