Mini Slide Switch for PCB — SS / SK / MSS / MSK Series, 3–8 Pin, Multiple Mounting Styles
Sourcing the right mini slide switch for a PCB project is harder than it looks. The wrong pin count, mounting orientation, or handle height means rework, a new board spin, or a switch that physically won't fit your enclosure. Electronics hobbyists, PCB designers, and small-batch manufacturers need a reliable source for SS, SK, MSS, and MSK series mini slide switches — with enough model variety to cover vertical, horizontal, SMD, and side-toggle layouts in one place.
This listing covers 21 models across the SS, SK, MSS, and MSK switch families, spanning 3 to 8 pins, 2-speed (SPDT/DPDT) and 3-speed (SP3T) configurations, and handle heights from 2mm (≈0.08") to 6mm (≈0.24"). Mounting options include vertical through-hole, horizontal through-hole, right-angle bent foot, SMD surface-mount, side-toggle, and pull-out styles. Single-row and double-row pin layouts are both represented. Pack sizes range from 2 to 300 pieces per order, making this listing suitable for prototyping and light production runs alike.
These mini slide switches are commonly used in Arduino and Raspberry Pi mode-selection circuits, DIY audio equipment input selectors and channel switches, handheld device power and function toggles, custom PCB control panels requiring compact SPDT or DPDT footprints, and consumer electronics repair where an original SS- or SK-series switch needs replacement.
🔌
Compatibility: Fits standard SS / SK / MSS / MSK series PCB footprints. Through-hole models are compatible with KiCad, Eagle, EasyEDA, and Altium library footprints for the corresponding part number. SMD variants require surface-mount reflow. Verify pin count, row configuration, and mounting orientation before ordering.

⚠️
Before ordering: Confirm the pin count, mounting orientation (vertical / horizontal / SMD), handle height, and row configuration for your specific model. Each variant has a unique footprint — mixing models may result in incompatible PCB pads. If you're unsure which model matches your application, contact us with your PCB layout or datasheet reference.
❓ Frequently Asked Questions
How do I choose the right mini slide switch for my PCB?
Work through three questions in order: (1) Positions: Do you need 2-position (on/on or on/off) or 3-position (on/off/on or on/on/on) switching? 2-speed = SPDT or DPDT; 3-speed = SP3T. (2) Poles: Are you switching one signal line (single pole, 3-pin) or two independent lines simultaneously (double pole, 6-pin)? (3) Mounting: Does your PCB layout call for vertical through-hole, horizontal right-angle, SMD, or side-toggle? Then check the handle height (2mm–6mm) against your enclosure clearance. Match all four criteria to the variant list above.
What is the difference between 2-speed and 3-speed slide switches?
A 2-speed switch has two stable positions — typically used for on/on (selecting between two circuits) or on/off (power switching). A 3-speed switch has three stable positions — useful for on/off/on (two active states with a center-off) or on/on/on (three-way signal routing). For simple A/B selection or a power toggle, 2-speed is sufficient. For three-way routing — such as selecting between two audio inputs plus a muted center position — choose 3-speed.
What voltage and current can these mini slide switches handle?
These mini slide switches are generally rated for low-voltage DC signal circuits, typically up to 12V DC at 0.3A–0.5A. They are designed for signal-level and light-load switching — such as toggling a microcontroller GPIO, selecting an audio signal path, or switching a low-current LED circuit. They are not rated for mains AC power (120V/240V) and should not be used in high-current applications. Contact us to confirm the exact rating for a specific model.
Are these switches suitable for outdoor or high-humidity environments?
These are standard PCB-mount slide switches without an IP-rated sealed housing. In most cases, they perform reliably in normal indoor environments. For outdoor use or high-humidity conditions, house them inside a sealed enclosure to protect the contacts from moisture and corrosion. If your application requires an IP-rated switch, contact us to confirm suitability before ordering.
What is the difference between vertical, horizontal, and SMD mounting?
Vertical (through-hole): Pins point straight down into the PCB; the actuator faces upward. Standard for most prototyping and custom PCB designs. Horizontal / right-angle: The switch body lies flat so the actuator faces the board edge or panel face — useful for side-actuated enclosures. SMD (surface-mount): Pads are soldered directly to the PCB surface without through-holes, saving board space and enabling automated pick-and-place assembly. Choose the style that matches your PCB layout and enclosure design.
Which model should I choose for an Arduino or Raspberry Pi project?
For most Arduino and Raspberry Pi projects, a 3-pin 2-speed vertical switch (such as SS12D10 or SS-12F44) is the most straightforward choice — it gives you a simple SPDT toggle for mode selection or power switching with minimal wiring. If you need to switch two independent signal lines at the same time (e.g., stereo audio or dual power rails), choose a 6-pin 2-speed DPDT model like MSS-22D18 or SK-22D07. For three-way selection, use a 3-speed model such as SS-13D07 or SK-13D07.
How do I find the right PCB footprint for these switches?
Search for the exact model number (e.g., SS12D10, MSS-22D18, SK-22D07) in your EDA tool's component library (KiCad, Eagle, EasyEDA, Altium). Most libraries include pre-built footprints for common SS/SK/MSS/MSK series switches. For SMD variants, use the SMD footprint matching the pad layout shown in the datasheet. If a footprint is not available in your library, contact us and we can provide the mechanical drawing or footprint file.
Can I order in bulk for production runs?
Yes. Each model is available in multiple pack sizes ranging from 2 pieces up to 300 pieces per order, with per-unit pricing that decreases at higher quantities. Select your model and pack size from the variant options above. For quantities beyond the listed options or for mixed-model bulk orders, contact us to discuss custom pricing and lead times.
