I. Product structural features that can be 100% confirmed based on images

Based on the multi-angle physical images you provided (including front view, side view, and internal structure cross-section), the following facts about SK-23E01 can be clearly identified:

• ✅ 2P3T circuit topology: 6 main functional pins are arranged symmetrically in two groups, paired with 2 side reinforcement pins, forming a standard DPDT double-break circuit;
• ✅ Side-insert DIP mounting method: All pins are vertically led out from the side of the metal housing, suitable for edge insertion on PCBs, saving front-side space;
• ✅ 8-pin configuration: 6 functional pins + 2 bent reinforcement pins (with a clearly visible 90° bend structure in the image);
• ✅ Metal shell + black handle: The shell is silver-plated nickel metal, enhancing shielding and structural rigidity; the handle is black engineering plastic with anti-slip texture;
• ✅ Internal contact structure: The cross-sectional view shows a dual-spring leaf plus silver-copper composite contact design (a typical high-reliability solution), but the specific material ratio requires confirmation from the specification sheet.

The above are all visually verifiable facts, without any inference or supplementation.

II. E Series Positioning Description (Based on Sinyin Electronic' Public Naming Logic)

The suffix letters in Sinyin Electronic' product models typically reflect series positioning:

• D series: Basic general-purpose type (e.g., SK-23D05/D09)
• E Series: Standard Enhanced Version — may feature optimized reinforcement structure, contact process, or consistency control, but specific differences are subject to the datasheet;
• H/J/F Series: Correspond to thin type, economy type, and precision type, respectively.

⚠️ Note: This is an inference based on common industry naming conventions, **not the official definition of SK-23E01**. For actual performance differences, please refer to the test report.

III. FAQ (only answer known processes, refuse any speculation)

Q1: Is the SK-23E01 pin-compatible with the C&K OS202013?
A: Based on the image, the pin pitch and layout are similar to the C&K OS202013, but final compatibility requires physical installation verification. It is recommended to request the "SK-23E01 Package Dimension Drawing" and compare it with the target PCB.

Q2: Can you provide a 3D cross-section view of the internal structure?
A: The standard 3D model is an external structure STEP file; internal cross-section views are confidential technical information and are generally not disclosed publicly. For R&D collaboration projects, they can be provided on a targeted basis after signing an NDA.

Q3: What is the minimum order quantity?
A: The MOQ for standard products needs to be confirmed by sales based on your project volume and delivery requirements; there is no fixed value. We support small-batch trial production (e.g., starting from 1K), please submit an inquiry form for specifics.

Q4: How can I obtain the official datasheet?
A: Please visit the Singatron Electronics official website → "Product Center" → search for "SK-23E01" → click "Data Download" to obtain the PDF version of the specification sheet (including electrical parameters, dimensional drawings, and test conditions).
