About DIP Switch

What is a DIP Switch?​
DIP Switches are miniature switches that are mounted onto PCBs and used to make settings on electronic devices.
Their name comes from having the same shape and array of terminals found in integrated circuits (dual inline package), thus abbreviated to DIP.
DIP Switches are categorized as setting switches, and the setting conditions are output as ON/OFF signals.

There are three operation methods for DIP Switches: Sliding Types, Piano Types and Rotary Types.

Sliding Types
Piano Types
Rotary Types

There are three different types of switching methods based on the operating part: Sliding Types, in which the operating part is slid, Piano Types, in which the operating part is pushed down and Rotary Types, in which the operating part is rotated. There are also variations in the shape of each operating part within these three categories.

Conclusion
DIP switches have been used to configure devices for decades and now have even been used to preconfigure IoT devices before they are deployed in the home or factory to limit downtime. Other common applications included programming garage door openers and remote controls, configuring PC motherboards, and enabling tests on industrial equipment without powering up the equipment.

There are many other forms of DIP switches. What they have in common is a combination of simplicity, flexibility, and low cost that means that they will continue to find new uses and applications.
