SK-24D02 Side-Handle Toggle Switch_2P4T Four-Position Precision Switching_D-Series Side-Insert DIP_Multi-Mode Control and Signal Routing Preferred_Sinyin Electronic
Industrial instrument multi-channel isolated switching | Medical equipment multi-speed safety control | High-end audio signal source routing | High-reliability domestic alternative solution
SK-24D02 is a 2P4T (double-pole, four-position) side-handle toggle switch of significant engineering value in Sinyin Electronic' D-Series. In complex systems requiring precise switching across four-level states, it can replace multiple 2P2T switches or complex relay arrays with a single component, greatly optimizing BOM cost and PCB space. The product features a metal shielded housing and side-insert DIP packaging, with a rated load of DC 50V 0.3A, and complies with RoHS 2.0 and REACH environmental directives. ⚠️ Note: For core parameters such as the truth table logic of each position, actuation force, and mechanical/electrical lifespan, please refer strictly to the official "SK-24D02 Specification Sheet" from Sinyin Electronic.

1. R&D Perspective: Why Choose 2P4T (DP4T) in Complex Systems?
In traditional hardware design, to achieve switching between four operating modes, engineers often need to stack multiple 2P2T switches or adopt an MCU + electronic analog switch (such as CD4052) solution. The SK-24D02's2P4T architectureprovides a superior physical-layer solution:

- Detailed Parameters
| Parameter Category | Project Specifications | Engineering/Procurement Remarks |
|---|---|---|
| Basic Information |
Model: SK-24D02 (D Series) Circuit Structure:2P4T / DP4T (Double Pole Four Throw) |
A single switch supports 4 independent positions, with double pole synchronized action, ensuring timing consistency across multi-channel signals. |
| Electrical performance |
Rated Load: DC 50V 0.3A (as indicated on the drawing) Contact Resistance/Insulation Impedance: Subject to the specification sheet |
Suitable for signal control and logic level switching in low-voltage, low-current applications; not recommended for directly driving high-power loads. |
| Mechanical and Dimensions |
Overall dimensions: 14.6 × 6.9 × 8.2 mm (drawing) Handle travel: 2 TRAVEL (approximately 2mm per position) |
Compact design, compatible with standard 2.54mm (0.1") grid PCBs; panel cutout should reserve clearance for handle swing. |
| Mounting and Pins |
Mounting method: DIP side mount (Side Mount THT) Pin configuration: 10 functional pins + bottom reinforcing pins |
Bottom metal reinforcing pins design significantly enhances resistance to mechanical vibration and pull forces after through-hole soldering. |
| Materials and Protection |
Housing: Nickel-plated metal (EMI interference protection) Handle: Black engineering plastic (anti-slip texture) |
The metal housing effectively isolates high-frequency signal crosstalk, making it suitable for use inside precision instruments and audio equipment. |
| Environmental Compliance and Regulations | RoHS 2.0 / REACH Certified | Meets global environmental export requirements for mainstream electronic products, with third-party test reports available upon request. |
