Sinyin SK-13D18 side-insertion three-position toggle switch | 1P3T (1 pole 3 positions 4 pins) | Dedicated board-edge bent-angle side-insertion reinforcement legs | Anti-slip anti-mistake patterned handle | Free samples and CAD/3D drawings
Sinyin Electronic original SK-13D18 is a DIP side-insertion type 1P3T (1 pole 3 position 4 Pin) 3-position slide switch. The product adopts a board-edge side-insertion structure, with dedicated bent reinforced solder tabs at both ends of the housing. After side-insertion into the very narrow edge of the PCB and soldering, it offers extremely strong resistance to peeling and torsional/pulling forces (>40N). The 4-pin design enables 3-position function switching, and the handle features an anti-slip texture with clear detent feel. Widely used in 3-speed small household appliances, multi-mode beauty devices, handheld test instruments, and audio equipment. Compliant with RoHS 2.0/REACH regulations, with free 2D/3D model downloads available.

[Structure and Function] SK-13D18 DIP board-edge side-insertion type 3-position slide switch (1P3T / 1 pole 3 position 4 pin)
SK-13D18 side-insertion 3-position slide switchis an electronic component designed by Shinyin Electronics specifically forBoard-edge side mounting, combining 3-position function switching with high-strength frequent push-pull operationA side-insertion electronic component designed for specific scenarios. The product adopts 1P3T (1 pole 3 position) circuit logic, with 4 conductive Pin terminals arranged at the bottom (1 COM common terminal + 3 function selection terminals).
Unlike ordinary horizontal switches, the SK-13D18 featuresside-angled metal wrapped solder tabs, after inserting through-hole vias on the PCB edge and soldering, the housing can offset lateral forces from the handle direction; meanwhile, the handle surface featuresanti-slip ribbed texture, significantly improving gear-switching experience with wet hands or during blind operation.
---【SK-13D18 Core Engineering Selling Points】
- 1. Side-Mount Locking: the two sides of the housing extend unique side-mount folded solder legs that tightly engage the PCB edge through-hole vias, achieving lateral anti-peel pull strength of up to >40N, eliminating pad detachment caused by frequent gear switching.
- 2. 1P3T Clear Three-Position Detent: the internal spring plate slot is precisely fine-tuned, providing distinct travel and crisp detent feel among positions 1-2-3, effectively preventing misoperation or incomplete gear engagement due to vague tactile feedback.
- 3. Anti-Slip Tactile Handle Design: The handle surface features deepened anti-slip ridges, facilitating precise gear sliding by the user within the narrow slit on the product casing's side wall.
- 4. Low Impedance and High-Temperature-Resistant Base: The internal contacts use a high-thickness silver plating process, offering low contact resistance (≤30mΩ). The insulating base withstands wave soldering high temperatures without blistering or loosening.
【Targeted Three-Position Application Scenarios】
| Key application areas | Matching three-position functional logic and end products |
|---|---|
| Portable small appliances and care devices | Side gear lock on portable shavers, three-level strength adjustment for beauty devices (off-low-high), three-speed wind control for handheld fans |
