【Product Overview】Single-row 3-pin two-position straight pins with holes and threaded miniature toggle switch (SPDT single-pole double-throw / panel thread locking / 3-pin solder lugs with holes / cylindrical metal lever / silver-plated contacts)

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

Standard single-row 3-pin design combined with the classic Metal threaded bushing + single-row 3-pin straight terminals with holes + cylindrical metal lever + SPDT (ON-ON) circuit , with the following core advantages:

• Standard metal threaded bushing panel locking: The head is equipped with a precision threaded bushing, paired with a standard nut and locking washer, allowing easy insertion through the enclosure panel hole for secure tightening, with excellent resistance to pull-out and vibration.
• 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: Threaded panel mounting ensures secure fastening, SPDT provides stable single-circuit control

The metal threaded bushing significantly enhances panel mounting strength, making it especially suitable for equipment with frequent panel operation; the silver-plated heavy-duty contacts offer low contact resistance, ensuring stable, bounce-free signal and power switching.

2. To Production Assembly and Process Engineers: Terminals with holes facilitate easy flying lead soldering, offering broad assembly adaptability

The terminal hole design ensures stronger soldering of flying leads with better anti-cold-joint performance; thread-locking installation is simple, making it ideal for manual or semi-automated assembly line integration.

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.
