What Is Slide Switch? Types and Usage Areas [2026 Guide]
If you are looking for simplest but most reliable control solution in your electronic projects, your answer may be Slide Switch.
Unlike buttons, with no need to hold pressed, these small heroes that keep their position once you slide the slider are indispensable for PCBs.
In this article, we explain slide switch from A to Z with Karina Elektronik experience.
What Is Slide Switch? How Does It Work?Slide switch is an electromechanical switch that connects or disconnects metal contacts inside with a linear slider movement.
Logic is very simple: You push slider to right, circuit closes, you push to left, circuit opens. Thanks to this mechanical structure, it is resistant to vibration and is not triggered accidentally.Pole and Throw Logic: How to Choose Correct Switch?Most confusing topic when buying slide switch is SPST, SPDT, DPDT codes. Actually very simple:SPST (Single Pole Single Throw): On / Off
Most basic model. 1 input, 1 output.
Only opens or closes circuit. Used as power switch.SPDT (Single Pole Double Throw): Selection Between Two Paths
1 common input, 2 different outputs. Allows you to switch from one circuit to another. Most classic example: Device switching between Battery and Adapter.DPDT (Double Pole Double Throw): Control Double Circuit At Same Time
2 inputs, 2 outputs (total 6 pins). Perfect for changing two separate circuits synchronously. Used for direction change in DC motors or complex mode selection in devices.SMD vs Through-Hole Slide Switch: Which Is Better For You?SMD (Surface Mount) Slide Switch:
Standard of modern production.
Takes very little space on PCB, suitable for automatic assembly machines and much more resistant to vibration.
If you do mass production, 90% your choice should be SMD.Through-Hole Slide Switch:
Legs pass through PCB hole. Very easy to solder by hand, mechanically very robust. Ideal for prototype development,
R&D and repair works.Karina Elektronik Slide Switch Technical Specifications
