Miniature Toggle Switch (Single Row 3 Pins with Holes / Two Positions ON-ON / Flat Lever Square Handle / Threaded Bushing Panel Mount / Single Pole Double Throw SPDT / Straight Solder Lugs)
Single-row 3-pin holed terminals | Two-position ON-ON (SPDT) switching | Flat square-handle metal rocker arm | Metal threaded panel fastening | Red housing with high insulation body | Precision high-conductivity silver-plated contacts | Suitable for instruments/audio modification/industrial control panels | Free samples and CAD drawings available
This single-row, two-position, square-handle, threaded miniature toggle switch (Toggle Switch SPDT 3 Pin Flat Lever) features a classic industrial-grade design with a "high-insulation red flame-retardant body + metal threaded bushing (including fixing nut/washer) + flat square metal operating lever + single-row 3-pin solder lugs with wire-through holes." The circuit configuration is single pole double throw (SPDT 3 Pin ON-ON two positions); swinging the square lever enables fast and stable switching between two circuits. The tail-end 3-pin terminals with holes are not only easy to solder, but the wire-through hook design also ensures physical fixation before soldering. The threaded neck supports through-hole panel mounting with a nut for secure installation, offering a clean appearance and crisp operating feel. Widely used in audio effects pedals, electronic test instruments, control panel switching, and equipment power/mode selection. 2D/3D drawings and free sample requests are available.

[Product Overview] Single-row 3-pin with holes, two-position, square-handle, threaded miniature toggle switch (Single Pole Double Throw SPDT / Flat Metal Lever / Panel Thread Locking / Silver-Plated Straight Solder Terminals)
Single-row, two-position, square-handle, threaded miniature toggle switch (Sub-Miniature Toggle Switch SPDT 3 Pin Flat Actuator) is a product specifically designed for Panel mounting, audio guitar effects pedals, instruments and meters, industrial control switching, and small control box modifications A high-precision lever-operated control switch crafted with excellence.
Standard single-row 3-pin design combined with the classic Flat square lever operating interface + panel thread-locking bushing + single pole double throw (SPDT ON-ON) circuit + high-conductivity silver-plated contacts , with the following core advantages:
- Flat square lever (Flat Toggle Lever) ergonomic operating arm: Compared to traditional cylindrical handles, the flat square lever design provides a larger finger contact area and clear directional recognition, with uniform lateral rocking force, a crisp feel, and superior visual texture.
- Threaded metal bushing (panel mount fastening): Comes with precision threads, and together with the included metal nut and lock washer, it can be easily fixed into mounting holes on various equipment panels, offering strong pull-out resistance and staying securely in place.
- Single-row 3-pin straight terminal with wire threading hole (easy to solder / secure wiring): The tail is made of high-conductivity copper alloy with silver-plated surface treatment, featuring a pre-drilled wire threading hole. It not only absorbs solder quickly and produces full solder joints, but also allows the wire core to be threaded and hooked before soldering, greatly enhancing tensile strength.
- Single-pole double-throw (SPDT ON-ON) two-position precise switching: The structure is extremely simple and reliable, with two stable positions. Toggling the lever smoothly switches the common pin (COM) between the other two wiring 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: Flat handle offers strong directional feel, SPDT switching is stable with no jitter
The flat square handle makes the operation direction clear at a glance, making it ideal for function/mode switching indicators; the silver-plated heavy-duty contact structure provides low contact resistance, with stable surge resistance and signal transmission performance.
2. To production assembly and process engineers: Terminals with holes are easy for wire threading, and threaded locking enables rapid assembly
The terminal hole design greatly reduces the risk of lap-solder detachment, and the soldering iron tins quickly; the sleeve thread follows standard specifications, and the panel nut is easy to tighten, improving assembly line efficiency.
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% testing for electrical continuity, switching feel, and click clarity of positions. Large quantities are kept in stock, ensuring fast sampling and efficient delivery.
