[Structure & Function] SK-22D14 DIP board-edge side-insert dual-circuit toggle switch (2P2T / 2-pole 2-position 6-pin)

SK-22D14 side-insert dual-circuit toggle switchis an electronic component designed by Shinyin Electronics specifically forapplications requiring PCB board-edge side mounting, simultaneous control of two circuits (such as full disconnection of power supply positive/negative terminals, dual-circuit signal switching), and anti-slip handling. The product adopts a 2P2T (double-pole double-throw / 6-pin) structure, with the base arranged in two rows totaling 6 functional pins.

Both sides of the housing feature reinforcedSide-angle metal fixed foot with folded corners, after penetrating deeply into the PCB edge via holes, it tightly clamps together, effectively dispersing the stress caused by the push-pull action of the dual contact blades; meanwhile, the handle surface is machined withmultiple deep anti-slip transverse ridges (knurled handle), significantly improving blind operation experience in wet hands or narrow gaps.

【SK-22D14 Dual-Channel Side-Insert Version Core Engineering Advantages】

• 1. 2P2T dual-channel synchronous switching: One switch handle simultaneously drives 2 sets of internal sliding contact blades, easily achieving dual-wire full power-off control or synchronous switching of dual-channel signals (such as L/R audio).
• 2. Anti-slip knurled handle with transverse ridges: The handle features deepened transverse anti-slip grooves, providing good friction and resistance to slipping when toggled through openings in the product housing side wall, with clear tactile feedback at the press-and-lock position.
• 3. High-strength locking for board-edge side insertionSide-fold edge-wrapped soldering tightly secures PCB edge vias, with lateral peel resistance up to >40N, preventing pad detachment caused by frequent gear switching.
• 4. Thick silver-plated low-resistance contact pieces: The internal moving and static contact pieces are both treated with multi-layer thickened silver plating, featuring low contact resistance (≤30mΩ), ensuring low heat generation and high conduction stability during dual-path overcurrent.
