A DIP switch is a manual electric switch that is packaged with others in a group in a standard dual in-line package (DIP). The term may refer to each individual switch, or to the unit as a whole. This type of switch is designed to be used on a printed circuit board along with other electronic components and is commonly used to customize the behavior of an electronic device for specific situations.
DIP switches are an alternative to jumper blocks. Their main advantages are that they are quicker to change and there are no parts to lose.
History[edit]
US patent 3,621,157 is the earliest known DIP switch patent. The patent discloses a rotary style DIP switch invented by Pierre P. Schwab. Schwab's patent application was filed on June 1, 1970, and the patent was granted on November 16, 1971.
The DIP switch with sliding levers was granted US patent 4012608 in 1976.[1] It was applied for 1974 and was used in 1977 in an ATARI Flipper game.[2]
Types[edit]
There are many different kinds of DIP switches. Some of the most common are the slide, rocker, piano (side), and rotary types.
Rotary DIP switches contain multiple electrical contacts, one of which is selected by rotating the switch to align it with a number printed on the package. Some have a knob that can be turned by fingers, or a small slot that require a screwdriver to change them. Typically, rotary types are available in two different types of output, 1) a binary encoded output, where 10 (BCD) or 16 (hex) choices are encoded into a 4-bit binary output, or 5 to 8 choices are encoded into a 3-bit binary output. 2) a rotary version of a multipole slide switch where one signal has a choice between multiple connections, such as SPDT, SP3T, SP4T.
The slide / rocker / piano types, which are very common, are arrays of simple single pole, single throw (SPST) contacts, which can be either on or off. This allows each switch to select a one-bit binary value. The values of all switches in the package can also be interpreted as one number. For example, seven switches offer 128 (27) combinations, allowing them to select a standard ASCII character. Eight switches offer 256 (28) combinations, which is equivalent to one byte.
A tri-state type DIP switch, with setting function (+, 0, -) obtain more codes than a binary DIP switch. For example, a 8 poles tri-state type offers 6,561 (38) combinations/codes which is much more than a 8 poles binary type offers 256 (28) combinations/codes. Especially suitable for encoding device such as remote controller.
The DIP switch package also has socket pins or mounting leads to provide an electrical path from the switch contacts to the circuit board. Although circuits can use the electrical contacts directly, it is more common to convert them into high and low signals. In this case, the circuit board also needs interface circuitry for the DIP switch, consisting of a series of pull-up or pull-down resistors, a buffer, decode logic, and other components.[3] Typically, the device's firmware reads the DIP switches when the device is powered on.
With the popularization of surface-mount technology, these switches are now commonly available in non-DIP surface-mount package types. They are, however, still referred to as 'DIP switches', as the term has become associated with the style of switch.
Contacts[edit]
Slide / rocker / piano DIP switches are commonly available in 1 to 12 contacts (positions) SPST,[4][5] though some are available as special order up to 30 contacts (positions).[6]
Applications[edit]
DIP switches were used extensively in ISA architecture of PC expansion cards to select IRQs and memory addresses. Before the advent of cheaper, battery-backed RAM, DIP switches were also often used on arcade games in the 1980s and early 1990s to enter game settings such as difficulty or the number of credits per coin. DIP switches were very commonly used to set security codes on garage door openers as well as on some early cordless phones. This design, which used up to 12 switches in a group, was used to avoid RF interference from other nearby door opener remotes or other devices. Current garage door openers use rolling code systems for better security.
These types of switches were used on early video cards for early computers to facilitate compatibility with other video standards. For example, CGA cards allowed for MDA compatibility.
After the late 1990s, DIP switches became less common in consumer electronics. Reasons include the trend toward smaller products, the demand for easier configuration through softwaremenus, and the falling price of non-volatile memory. However, DIP switches are still widely used in industrial equipment because they are inexpensive and easy to incorporate into circuit designs, and because they allow settings to be checked at a glance without powering the system on.
DIP switches are still used in some remote controls to prevent interference; for example, to control a ceiling fan (and its light fixture) that was retrofitted to a single-circuitjunction box. The DIP switches set a different radio frequency or address for each transmitter/receiver pair, so that multiple units can be installed without unintentionally controlling each other.

A dual in-line package (DIP) switch is a small packaged set of switches, commonly installed on circuit boards, that are used in consumer and industrial devices. DIP switches, sometimes written as 'dip switches,' are on-off switches arranged in a line and packaged in a small box or housing. A DIP switch's function is to provide a range of electrical inputs to a computer or electronic device based on the position of the switches.The switches can be slide, toggle or rotary styles. As each switch is positioned on or off, the DIP switch can create an electrical signal that imitates a binary signal common to computers that use the numerals 0 and 1 to perform complex calculations. A rotary DIP switch has advantages over simple switches by permitting multiple choices that result in different electrical signals from the switch, versus a simple 'on' or 'off' position.DIP switches were common on computer circuit boards until the 1990s, when digital switches began to replace them.
Consumer applications such as door openers, ceiling fan remote controls and wireless phones continued to use DIP switches into the 21st century. Home remote control devices can benefit from a DIP switch because the device might interfere with other electronics in the home. When a DIP switch is connected to a remote control transmitter, changing the switch settings can remove interference by creating a different frequency for the remote control. Binary control is still a valuable use of a DIP switch. Computers use processors that perform calculations by designating a value of 0 or 1. DIP switches mimic this effect because each switch position is 'on' or 'off,' the manual equivalent of a 0 or 1. For small consumer electronic products, a DIP switch might be a cost-effective substitute for digital control processors, particularly when the device needs to have different switch positions available to the user.As digital processors have replaced mechanical switches and components since the 1970s, so have digital DIP switches begun to replace mechanical styles.
A digital switch performs an identical function to a mechanical switch, but there is no physical switch to access. Digital DIP switches are managed from a control panel or computer screen.
The interface might appear similar to a mechanical switch, with virtual switches that can be turned on or off with a keyboard or computer mouse. There is no longer a mechanical switch to manipulate, however, and the switch components are greatly reduced in size. @allenJo - Well there’s no software based solution for garage door opener DIP switches.
Dip Switch
Garage door openers use DIP switches for a number of purposes, one of which is to program the remote and enable it to work with the receiver.This is fine as far as it goes. However, if you lose your remote and try to buy a “universal” remote you may be out of luck. They may not have the correct dip switch settings to get them to work with your existing receiver.The only solution in that case would be to buy both a new remote and receiver as a complete unit. @miriam98 - I prefer using the software based version of setting up these electrical switches.

I don’t like squinting and having to fiddle around with mechanical switches.If you install certain computer devices they usually come with a CD Rom nowadays which will bring up the control panel for adjusting your device’s settings.Some common devices that can be controlled in this manner are different kinds of cards that you install in your PC. You can usually adjust any kind of settings or fix any problems with these cards simply by using the control panel.This is so much easier and it beats installing a device, only to find out you didn’t set the dip switch correctly, and then having to open up your computer and readjust it in my opinion. Actually while the DIP switches may not be used in motherboards as much, you still find them in hard drives.

When you install an internal hard drive you have certain dipswitch settings.You have to choose the right one to work with your hard drive. There is a manual and illustration that will show you how to do it. The purpose of the DIP switch settings is to determine which hard drive will be the primary and which one will be the slave.If you mess this up then your hard drives won’t work properly. Nowadays you can have multiple hard drives, including external drives, so it’s important to get this right. Kabhi toh paas mere aao mp3.
