Mini Slide Switch On/Off PCB Mount — Reliable 2-Position Control for Compact Electronics

When you're deep into a DIY electronics build and need a clean, space-saving way to control power or toggle between circuit states, a bulky rocker switch just doesn't cut it. The SK12D07VG3 mini slide switch is built for makers, hobbyists, and engineers who need a dependable micro toggle that fits tight PCB layouts without sacrificing tactile feedback.

Each switch is a single-unit SPDT (Single Pole Double Throw) slide switch with 3 pins and a 2-position (ON/OFF) actuator. The compact body measures approximately 8mm × 4mm × 3.5mm, with a 3mm (≈1/8") actuator handle height. Pin pitch is standard 2.54mm (0.1"), compatible with breadboards and through-hole PCBs. Available in quantities of 20, 40, 60, 80, or 100 pieces per order.

Typical use cases include Arduino power switches, battery-powered gadget on/off controls, LED strip mode selectors, DIY enclosure panel switches, and prototype circuit boards — anywhere a compact PCB slide switch for microcontroller projects is needed.

⚠️ This switch is rated for low-voltage signal circuits (typically up to 0.3A / 6V DC). Confirm your circuit's current and voltage requirements before installation. Not suitable for mains or high-current applications.

🔌 Compatible with standard 2.54mm (0.1") pitch breadboards, perfboards, and through-hole PCB layouts. Suitable for Arduino, Raspberry Pi, ESP32, and similar low-voltage microcontroller platforms.

✅ Key Features of These Mini PCB Slide Switches

📐Compact PCB Footprint — The slim body (approx. 8mm × 4mm) fits tight board layouts where space is at a premium, making it ideal for compact Arduino slide switch on/off applications.
🔩Standard 2.54mm Pin Pitch — Three through-hole pins spaced at 0.1" drop directly into breadboards and standard PCB footprints with no adapter needed.
🎚️Tactile 2-Position Actuation — The slide actuator clicks firmly between ON and OFF positions, giving clear mechanical feedback so you always know the circuit state.
⚡Low-Voltage Signal Switching — Designed for 3.3V and 5V logic-level circuits, this 3-pin micro toggle switch handles signal and light-load power switching reliably.
🏭Consistent Batch Quality — Available in packs of 20 to 100 pieces, each unit follows the SK12D07VG3 specification for consistent dimensions and electrical performance across your build.
🛠️Versatile Mounting Options — The 3mm handle height suits both direct PCB soldering and panel-mount cutout installations in DIY enclosures and project boxes.

❓ Frequently Asked Questions

How do I choose the right quantity for my project?

Generally, estimate the number of switching points in your circuit and add 10–20% as spares. For small Arduino or breadboard projects, 20 pcs is typically sufficient. For production runs or classroom kits, 60–100 pcs is a more practical starting point.

What current and voltage can this slide switch handle?

The SK12D07VG3 is rated for low-power signal switching. It typically handles up to 0.3A at 6V DC. It is not designed for mains voltage or high-current loads — always verify your circuit requirements before use.

Can this switch be used outdoors or in humid environments?

This switch is generally intended for indoor PCB applications. It does not carry an IP rating, so prolonged exposure to moisture or outdoor conditions is not recommended without additional enclosure protection.

Is this switch compatible with standard breadboards and PCBs?

Yes. The SK12D07VG3 features a standard 2.54mm (0.1") pin pitch, making it compatible with most breadboards, perfboards, and custom PCB layouts that follow standard through-hole spacing.

What is the difference between a 2-position slide switch and a 3-position one?

A 2-position switch (like this one) toggles between ON and OFF — connecting or disconnecting the circuit. A 3-position switch adds a center-off or alternate-circuit position. For simple power control, a 2-position switch is the straightforward choice.

Will this switch work with Arduino, Raspberry Pi, or similar microcontroller projects?

Yes. This mini slide switch is widely used in Arduino, Raspberry Pi, and other microcontroller projects for power switching or mode selection. Its 3.3V and 5V signal-level compatibility makes it a practical choice for low-voltage digital circuits.

How is the 3mm handle length measured, and does it affect installation?

The 3mm refers to the height of the actuator (toggle handle) above the switch body. This compact profile is designed for flush or near-flush panel mounting where space is limited, such as inside enclosures or on compact PCBs.
