8-Pin ON-OFF-ON Slide Switch SMD SMT — Compact 3-Position Control for PCB Projects
When your PCB layout leaves no room for a bulky toggle and you need reliable three-way switching between two signal paths, finding a compact, solderable solution can slow down your entire build. Electronics hobbyists, PCB designers, and DIY kit builders working on space-constrained boards need a switch that fits the footprint, holds its position, and survives the soldering process without lifting pads.
Each pack contains 5, 10, 15, or 20 pieces of the same 8-pin 3-position ON-OFF-ON mini horizontal slide switch, designed for SMD/SMT PCB mounting. The switch body is compact — typical of mini slide switches used in low-profile PCB assemblies — with 8 solder pins arranged for horizontal, surface-mount installation. Available in multiple pack sizes to match your project scale.
These switches are well-suited for DIY electronics projects such as Arduino and Raspberry Pi accessory boards, custom RC transmitter panels, portable audio selector circuits, and small consumer electronics prototypes where a 3-position horizontal slide switch for PCB is needed in a tight footprint.
🔌
Compatibility: Designed for SMD/SMT PCB mounting. Compatible with standard PCB design tools including KiCad, Eagle, and Altium footprint libraries. Verify pin pitch and body dimensions against your board layout before soldering.
⚠️
Confirm before ordering: Pin pitch, body dimensions, and exact current rating vary by production batch. Please contact us or check the product datasheet to confirm specifications match your PCB footprint.
✅ Key Features of These 8-Pin ON-OFF-ON Horizontal Slide Switches
-
🔀
True 3-Position Switching — ON-OFF-ON configuration lets you select between two independent circuits or signal paths, with a stable center-off position — ideal for DIY selector switch PCB builds.
-
📐
Horizontal SMD Form Factor — Low-profile horizontal mounting keeps the switch flush with the PCB surface, saving vertical clearance in enclosures and stacked board assemblies.
-
🔩
8-Pin Layout for Stable Mounting — Eight solder pins distribute mechanical stress across the board, reducing the risk of pad lift during actuation — a common issue with 4-pin mini slide switches.
-
🛠️
Hand-Solderable or Reflow Compatible — Works with both fine-tip hand soldering and standard SMT reflow processes, giving flexibility to hobbyists and small-batch assemblers alike.
-
📦
Multi-Pack Options — Available in packs of 5, 10, 15, or 20 pieces, so you can stock exactly what your project or kit production run requires without overpaying for bulk minimums.
-
⚡
Low-Power Signal Switching — Rated for low-voltage DC signal circuits, making these switches a practical choice for microcontroller input selection, mode switching, and logic-level routing on DIY electronics boards.

❓ Frequently Asked Questions
How do I choose the right quantity pack for my project?
For prototyping or one-off builds, a pack of 5 is generally sufficient. For small production runs or kits, packs of 10–20 offer better per-unit value. Consider ordering extras — SMD components are easy to lose during hand-soldering.
What does the 3-position ON-OFF-ON configuration mean?
The switch has three stable positions: the left position connects one circuit (ON), the center position breaks all connections (OFF), and the right position connects a second circuit (ON). This makes it suitable for selecting between two signal paths or power sources.
What is the current and voltage rating of this slide switch?
Mini SMD horizontal slide switches of this type are typically rated at 0.3A–0.5A at 6V DC. They are designed for low-power signal switching in PCB circuits, not for mains or high-current loads. Always verify the datasheet for your specific application.
Can this switch be used outdoors or in humid environments?
This switch is designed for indoor PCB use and is generally not rated for outdoor or high-humidity environments. In most cases, SMD slide switches lack conformal coating or IP-rated sealing. For outdoor use, consider a sealed or waterproof switch variant.
Is this switch compatible with standard PCB footprints?
Yes — 8-pin horizontal slide switches in this form factor typically follow a standard SMD footprint compatible with common PCB design tools like KiCad, Eagle, and Altium. Always verify pin pitch and body dimensions against your PCB layout before ordering.
Can I hand-solder this SMD switch, or does it require reflow?
This switch can generally be hand-soldered with a fine-tip soldering iron and flux. However, SMD components with tight pin pitch benefit from reflow soldering for consistent results. Use low-temperature solder paste and a hot air station if available.
What is the pin pitch of this 8-pin slide switch?
Mini SMD horizontal slide switches of this type typically have a pin pitch of 1.27mm (0.05") or 2.0mm (≈0.079"). Please confirm the exact pitch against your PCB footprint before soldering. Contact us to confirm the specific pitch for this SKU.
