[Function and Structure] SK-22D02 DIP board-edge side-mount dual-channel slide switch (2P2T / 2-pole 2-position 6-pin)

SK-22D02 side-mount dual-channel slide switchis an electronic component designed by Shinyin Electronics specifically forRequires PCB board-edge side mounting, and must simultaneously control two independent circuits (such as dual-break of power supply positive/negative terminals, or linked control of signal and power). The product adopts a 2P2T (double-pole double-throw / 6-pin) Structure, internally containing two sets of independent sliding contact systems.

To accommodate the push-pull friction caused by the dual-channel contacts, the SK-22D02 adopts a reinforcedSide-angle metal fixed foot with folded corners, which tightly grips after insertion into the PCB board-edge through-holes, and can withstand high-intensity lateral push-pull from the handle direction after soldering; the handle head is equipped withanti-slip dot matrix texture, ensuring no slipping during high-frequency toggling.

【SK-22D02 Dual-Channel Side-Insert Version Core Engineering Advantages】

• 1. 2P2T Dual-Channel Synchronous Control: A single toggle action simultaneously actuates 2 independent contact sets, making it ideal for safety circuit designs requiring "full pole disconnection (both lines fully cut)" or "power + data synchronous switching."
• 2. High-Strength Board-Edge Side-Insert Locking: The housing extends unique angled reinforcing solder tabs on both sides, which firmly interlock with the PCB board edge, providing lateral peel resistance up to >40N, preventing pad lifting and solder joint detachment.
• 3. 9-Point Anti-Slip Tactile Handle: The handle top features an array of raised dots, increasing finger friction for crisp, decisive switching even in narrow gaps along device side walls.
• 4. Low-Impedance Thickened Silver-Plated Contacts: All 6 pins and internal moving contact blades undergo multi-layer thickened silver plating, achieving low contact resistance (≤30mΩ), maintaining low heat generation and high conduction stability under dual-channel power operation.
