[Product Overview] Single-row 3-pin, two-position, straight-pin with holes, extended center pin, threaded miniature toggle switch (SPDT single-pole double-throw / panel thread locking / extended center COM pin anti-short-circuit / silver-plated contacts)

Single-row, two-position, straight-pin, 3-pin with holes, extended center pin, threaded miniature toggle switch (Threaded Bushing Toggle Switch SPDT 3 Pin Extended Center Pin Solder Lug) is a product specifically designed for Equipment enclosure panel hole locking, efficient manual flying-lead soldering, anti-short-circuit assembly, audio equipment and industrial control panels A high-reliability rocker control switch crafted.

Standard single-row 3-pin design combined with the classic Metal threaded bushing + extended center common pin (COM) with hole terminal + cylindrical metal lever + SPDT (ON-ON) circuit , with the following core advantages:

• Extended center common pin (COM pin) anti-error design: The center pin is significantly longer than the two side pins, greatly improving the recognition of the common wire on the production line and reducing assembly wiring errors; at the same time, it increases the spacing between solder joints, effectively avoiding the risk of wire-tip bridging short circuits during manual soldering.
• Standard metal threaded bushing panel locking: Equipped with a precision threaded bushing at the top, paired with standard nuts and lock washers, it can be easily passed through the panel opening for secure tightening, offering excellent pull-out resistance and vibration resistance.
• Straight lug with hole (Solder Lug / PC Terminal) dual-purpose terminalThe pins feature precision silver plating and are drilled with holes, facilitating both wire-through soldering for secure attachment to prevent detachment and vertical insertion soldering onto the PCB motherboard.
• Classic cylindrical metal toggle lever (crisp tactile feel)Pressing and toggling provide a clear, natural tactile response, with crisp and decisive position switching without hesitation. The metal lever's surface coating resists corrosion and delivers extremely high mechanical durability.
• Single-pole double-throw (SPDT ON-ON) precise switching: Features a minimalist and efficient structure with two stable positions; toggling the handle smoothly switches the common terminal (COM) between the other two terminals.
• 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: Extended COM pin prevents lap short circuits, threaded retention ensures firm fastening

The physical isolation of the long and short pins increases the electrical clearance, avoiding solder joint short circuits caused by operational vibration or accidental contact; the silver-plated strong contact points offer low contact resistance, ensuring stable signal and power switching without jitter.

2. To Production Assembly and Process Engineers: High recognition for fast assembly, easy soldering with holes

The extended middle pin allows workers to quickly solder the common wire without repeatedly verifying pin positions, significantly improving production line soldering efficiency; the terminal holes make flying wire tinning more secure.

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

Produced on Dongguan Sinyin Electronic' mature automated production lines, with 100% inspection for conductivity, thread flatness, and tactile detent feel, and large-volume stock availability, ensuring rapid sampling and high-efficiency delivery.
