A DIP switch (Dual In-line Package switch) is a compact electromechanical device used to manually configure electronic circuits. DIP switches are widely used in PCB design, embedded systems, industrial equipment, communication devices, and electronic prototyping.
ATO offers a complete range of SPST DIP switches, including mechanical, surface mount, and side mount models with 1 to 12 positions. Whether you need simple ON/OFF circuit control or multi-position hardware configuration, you can find the right DIP switch for your application.
DIP Switch Types
Different types of DIP switches are available to accommodate various PCB layouts, assembly methods, and circuit configuration requirements. Most DIP switches use a standard 2.54 mm (0.1 inch) pin pitch, making them compatible with a wide range of PCBs, breadboards, and electronic devices.
- Mechanical DIP Switches: Mechanical DIP switches are SPST (Single Pole Single Throw) devices that provide simple ON/OFF control for individual circuits. They are commonly used in small electronic projects, development boards, and basic hardware configuration applications.
- Surface Mount DIP Switches: Surface mount DIP switches are designed for compact PCB layouts and automated assembly processes. Available in 5–8 positions, they are widely used in embedded systems, industrial electronics, and space-constrained circuit designs.
- Side Mount DIP Switches: Side mount DIP switches are installed along the edge of the PCB to maximize board space while maintaining easy access for configuration. They are commonly used in industrial control equipment and communication devices requiring 10–12 position configurations.

How to Choose the Right DIP Switch
Selecting the correct DIP switch depends on your PCB layout, circuit requirements, and intended application. Consider these factors:
Number of Positions
- Determines how many circuits the switch can control.
- 1–4 positions for small projects, 5–8 for embedded systems, 10–12 for industrial devices.
- Extra positions allow future expansion.
Mounting Type
- Through-Hole: Strong mechanical stability, easy hand soldering.
- Surface Mount (SMD): Compact, ideal for automated PCB assembly.
- Side Mount: Saves PCB space, suitable for high-density boards.
Pin Configuration
- Ensure pin count and spacing match your PCB footprint.
- Standard pitch is 2.54 mm.
Circuit Type
- SPST: Simple ON/OFF control.
- SPDT: Switches between two circuits (less common).
Application Requirements
- DIY / Prototyping: Small mechanical switches are sufficient.
- Embedded Systems: Medium-position SMD or through-hole for automation.
- Industrial / Communication: High-position side-mount for complex configurations.
Common DIP Switch Applications

- Offers hardware-based customization without software updates.
FAQ
Q: How does a DIP switch work?
A: Each switch inside the package opens or closes a circuit. When switched ON, current can flow; when switched OFF, the circuit is disconnected.
Q: What is the standard pin spacing of a DIP switch?
A: Most DIP switches use a standard 2.54 mm (0.1 inch) pin spacing compatible with PCBs and breadboards.
Q: Can DIP switches be reused?
A: Yes. DIP switches are designed for repeated operation and can be switched ON and OFF many times throughout their service life.
Q: Can DIP switches be used with microcontrollers?
A: Yes. DIP switches are frequently used to configure microcontroller addresses, operating modes, and hardware settings without changing firmware.
Q: What is the difference between a DIP switch and a jumper?
A: A DIP switch allows configuration changes by simply toggling a switch, while a jumper requires physically moving a connector between pins. DIP switches are generally more convenient for frequent adjustments.
