[Product Overview] Single-row 3-pin, two-position, straight-terminal miniature toggle switch (SPDT single-pole double-throw / vertical PCB through-hole / cylindrical metal lever arm / smooth bushing / silver-plated pins)

Single-row, two-position, straight-terminal miniature toggle switch (Vertical PCB Toggle Switch SPDT 3 Pin Straight Terminal) is a product specifically designed for Vertical through-hole soldering on PCB motherboards, audio equipment, instruments, meters, and high-density circuit boards A high-reliability rocker control switch crafted.

Standard single-row 3-pin straight-terminal design combined with classic Vertical through-hole pins + precision smooth metal bushing + cylindrical metal lever arm + SPDT (ON-ON) circuit , with the following core advantages:

• Single-row 3-pin vertical through-hole silver-plated pins: The pins are precision silver-plated, offering excellent solderability, and can be directly inserted vertically through holes and soldered onto the PCB, occupying minimal board space with a very compact layout.
• Classic cylindrical metal toggle lever (crisp tactile feel): The toggle and press feedback is clear and natural, with crisp and decisive position switching. The metal lever arm surface is coated for corrosion resistance, ensuring extremely high mechanical durability.
• Fine smooth metal sleeve design: Compact smooth sleeve without external thread texture, clean and neat appearance, suitable for embedded panels or direct board-mounted exposed installation.
• Single-pole double-throw (SPDT ON-ON) precise switching: Minimalist and reliable structure with two stable positions; rocking the handle smoothly toggles the common pin (COM) between the other two terminal pins.
• High-insulation, heat-resistant housing with long-life design: Adopts a high-quality red/black engineering insulating plastic base and anti-corrosion metal top cover, with high flame retardancy rating, excellent temperature resistance, and a mechanical switching life of over 50,000 cycles.

[Core Value and Procurement Decision Factors for Different Customer Segments]

1. To electrical and hardware engineers: Small footprint, stable SPDT single-circuit control

Single-row 3-pin straight pin structure greatly saves PCB routing space; silver-plated strong contacts offer low contact resistance, ensuring stable signal and power switching without jitter.

2. To production and process engineers: Through-hole PCB reflow soldering is smooth, with excellent solder wetting

Standard 2.54mm pin pitch design, suitable for wave soldering and automated pin insertion reflow processes; silver-plated pins resist oxidation, improving first-pass soldering yield on the assembly line.

3. To B2B Procurement and Supply Chain Managers: Source factory quality assurance, complete certifications, and worry-free delivery

Produced on mature automated production lines at Dongguan Shinyear Electronics, with 100% testing for electrical continuity and crisp detent feel of the switch positions; large ready stock ensures fast sampling and efficient delivery.
