What is a DIP Switch PCB in Electronics?

DIP literally means “Dual In-Line Package.” It is an electronic term used for types of a switch. DIP switch is a group of small-size manual switches for electronics. They are specially designed to be grouped with other printed circuit boards. The term DIP either refers to a single switch, a unit of multi-switch, or the complete unit. 

DIP switches are essentially used to modify a device’s operating mode by allowing users to manage the electric current that flows around a PCB, electronic accessory, and expansion card. 

DIP switches provide the user with the ability to tailor the behavior of the electronic equipment in question when mounted on a PCB along with other components, enabling complete leverage over the specific task the device will conduct in a variety of applications and defined scenarios. DIP switches are commonly displayed as a series of small toggle (on/off) switches installed consecutively on a piece of high-temperature thermoplastic polymer, much like a number of miniature traditional light switches.

A group of DIP switches nearly always requires considerable dexterity from the user to toggle every switch between the state of on and off because they are often quite small as a whole component. In actual use, this function is frequently carried out with the tip of a pointed pencil or another appropriately shaped tool because individual switches are typically too small to be operated with a finger.

DIP switches are often widely used, reasonably priced components that make it easy to choose and switch between different hardware or device configurations. DIP switches have the drawback of requiring the user to physically open the device in order to access the PCB and then manually activate the switches from there. However, they are typically far less expensive than alternatives like programmable chips or programming control panels.

This article gives you a detailed insight into the types, forms, and functions of a group of DIP switches and the various types and varieties of devices and applications available in the market. 

Uses of DIP Switch PCB

Due to the downscaling trend and the decreasing costs of other equivalent solutions, DIP switches are less popular than they previously were. Nonetheless, they continue to be utilized in a variety of test circuits and industrial applications. 

This is due to the fact that physical DIP switches provide a very affordable choice for system control that is also incredibly simple to connect to an existing Printed circuit board or prototype circuit model. DIP switches can significantly decrease the need for extra hardware to conduct a wider range of output jobs by providing a quick and handy way to physically observe the settings that are currently chosen without turning the system on first.

Application of DIP Switch PCB

In modern circuits and devices, the most widely used applications of DIP switches include the following.

The setting up of numerous possibilities for Computer hardware and accessories. This comprises expansion modules, motherboards, hard drives, video cards, modems, as well as other add-ons or auxiliary parts. There are still many garage doorway systems that use DIP switches.

They’re frequently used in universal remote controllers to stop electrical interference from causing accidental device control. For each pair of receivers and transmitters in this scenario, a distinct radio frequency will be configured using the DIP switch.

How does DIP Switch PCB Work?


Conventional surface-mounted DIP switches are offered as an arrangement of straightforward two-terminal (1/0 or on/off) mechanical switches that have been constructed inside a thermoplastic polymer block container. Although technically, they are just an alternative to the traditional jumper; they are frequently referred to as “jumpers” despite the fact that their general purpose is extremely similar.

The “dual in-line” part of the acronym relates to how the contact pins on the underside of the DIP switch block, which connect to the PCB or prototype directly, are arranged. They are placed in two parallel lines, hence the name “dual in-line.” In general, a given module will have twice quite so many contact wires as switches.

When choosing a certain device function and needing to toggle many switches to get the desired output mode, DIP switches come in handy. Among the most frequent uses for a DIP switch is on the motherboard of a computer, where different configuration options can be accessible by flipping various switches.

A typical DIP switch could include one, two, four, seven, eight, ten, sixteen, or more toggle, slide, rocker, and rotatory slide installed on one tiny block. Although DIP switches are simple parts, their value lies in the fact that by placing numerous toggles in parallel, each one can be individually switched to the 1/0 position, potentially opening up a vast array of possible combinations to explore.

With a typical DIP switch matrix, every single toggle is disconnected from the others. A flexible suspension underneath the switch reacts to the motion of the rocker or slider and bends gently up or down in order to shut or open a passive contact below when a switch on such a DIP switch is shifted between its on and off settings. Correspond with a wide range of potential device outputs/functions.

As per their safe operational power, improved power quality, and voltage, DIP switches are generally divided into groups for various functions and applications. Users must follow and adhere to the manufacturer’s guidelines while using a specific DIP switch in order to avoid issues like a self-welded switch and electric curving while switching that could result in performance instabilities or device breakage.

Benefits of DIP Switch PCB

The following are just a few of the numerous advantages of DIP switch matrices in specific circuits, design procedures, and types of devices:

  1. For certain higher-end Dual In-line Package switch versions, gold contacts are frequently a choice, providing significantly improved durability and efficiency.
  2. They serve as a practical upgrade to more worn-out jumpers.
  3. Units range from 1 to 32 poles, providing a wide range of utility and versatility.
  4. In busy production operations, longer poles upon certain designs help save loading times.
  5. In order to place DIP switches on a Printed Circuit Board or prototype, their poles can easily be adjusted by being chopped to the appropriate level.


Although there has been a slight decline in the use of DIP switches in some contemporary applications due to the rising cost-effectiveness of application control panels as well as computer-controlled onboard chips, DIP switches still are viewed as a very appealing option in a variety of design workflows, device testing, and industrial settings.
