1. Core Value of the 2P3T Circuit Structure (Based on User Confirmation + Image Verification)

The SK-23H04 adopts a2P3T (Double Pole Three Throw)design. Compared to common 2P2T models, its core advantages are:

• ✅ Three-Position Switching: Supports "On-Off-On" or "A-B-C" three states, meeting multi-mode control requirements (such as low speed/stop/high speed, channel 1/channel 2/off);
• ✅ Double Pole Synchronous Switching: Two independent circuits switch synchronously under the same handle operation, ensuring signal consistency and safety;
• ✅ Pin layout verificationFrom the bottom view you provided, the 8 main function pins are arranged symmetrically in two rows, with a reserved empty position or shorting strap in the middle (depending on the specific sub-model), consistent with the standard 2P3T package characteristics.

⚠️ Note: The middle position of the 2P3T switch may be either "open circuit" or "short circuit" logic. Be sure to consult the datasheet'struth tableto confirm the actual on/off relationship.

II. Structural features that can be 100% confirmed based on the images

From the two physical images (front + bottom), the following facts can be clearly identified:

• ✅ H-series marking: The laser-engraved "SK-23H04" text on the side of the housing is clearly visible;
• ✅ Side-mount DIP structure: The pins are led out vertically from the side of the metal shell, suitable for PCB edge insertion mounting process;
• ✅ Reinforcement foot design: Two reinforcement pins bent 90° laterally are visible at the bottom, enhancing vibration resistance and soldering strength;
• ✅ Handle anti-slip texture: The black handle surface features horizontal stripes, improving operational feel and recognizability.

III. FAQ (Only answer known processes, refuse to speculate)

Q1: Is the middle position of SK-23H04 open circuit or short circuit?
A: This parameter is a critical electrical characteristic, and may vary between different batches or sub-models.Must refer to the "Contact Arrangement" or "Truth Table" section in the official datasheet to confirm, and must not infer based on experience.

Q2: Is it pin-compatible with the C&K OS203013?
A: From the image, the pin spacing is similar to the C&K OS203 series, but the middle pin definition of the 2P3T model often differs. It is recommended to request the "SK-23H04 Package Dimension Drawing" and compare it one by one with the target PCB pads.

Q3: Can you provide a screenshot of the truth table for the 2P3T?
A: Yes. Please obtain the full specification sheet via the "Downloads" section on the official website, where page 3 typically includes the detailed contact switching timing diagram and truth table.

Q4: 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.
