in a standard <a href="/wiki/Dual_in-line_package" title="Dual in-line package">dual in-line package</a> (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 <a href="/wiki/Printed_circuit_board" title="Printed circuit board">printed circuit board</a> along with other <a href="/wiki/Electronics" title="Electronics">electronic</a> components and is commonly used to customize the behavior of an electronic device for specific situations. </p><p>DIP switches are an alternative to <a href="/wiki/Jumper_(computing)" title="Jumper (computing)">jumper</a> blocks. Their main advantages are that they are quicker to change and there are no parts to lose. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=DIP_switch&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>US patent 3621157, filed in 1970 by Pierre Schwab,<sup id="cite_ref-Patent3621157_1-0" class="reference"><a href="#cite_note-Patent3621157-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> is the earliest known DIP switch patent, which discloses a rotary style DIP switch. </p><p>US patent 4012608, filed in 1975 by Joseph Lockard,<sup id="cite_ref-Patent4012608_2-0" class="reference"><a href="#cite_note-Patent4012608-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> is a DIP switch with sliding levers, the modern DIP switch. </p> <div class="mw-heading mw-heading2"><h2 id="Types">Types</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=DIP_switch&action=edit&section=2" title="Edit section: Types"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The slide, rocker, and piano types, which are very common, are arrays of simple <a href="/wiki/Single_pole,_single_throw" class="mw-redirect" title="Single pole, single throw">single pole, single throw</a> (SPST) contacts, each of 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 (2<sup>7</sup>) combinations, allowing them to select a standard ASCII character. Eight switches offer 256 (2<sup>8</sup>) combinations, which is equivalent to one <a href="/wiki/Byte" title="Byte">byte</a>. </p><p>A tri-state type DIP switch can be in one of three positions (+, 0, −) which allows more codes than a binary DIP switch. For example, 8 pole <a href="/wiki/Three-state_logic" title="Three-state logic">tri-state</a> DIP switches offer 6,561 (3<sup>8</sup>) combinations/codes compared to 8 pole binary switches' 256 (2<sup>8</sup>) combinations/codes. This makes them especially suitable for encoding devices such as a remote controller. </p><p>Rotary DIP switches contain multiple <a href="/wiki/Electrical_contact" title="Electrical contact">electrical contacts</a>, 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 requires a <a href="/wiki/Screwdriver" title="Screwdriver">screwdriver</a> to change them. Typically, rotary types are available in two different types of output, 1) a binary encoded output, where 10 (<a href="/wiki/Binary-coded_decimal" title="Binary-coded decimal">BCD</a>) 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. </p><p>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.<sup id="cite_ref-Patent5010445_3-0" class="reference"><a href="#cite_note-Patent5010445-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Typically, the device's <a href="/wiki/Firmware" title="Firmware">firmware</a> reads the DIP switches when the device is powered on. </p><p><a href="/wiki/Single_in-line_package" class="mw-redirect" title="Single in-line package">Single in-line</a> SIP switches are also available, which only have one row of pins instead of the two rows of pins in DIP packages. This saves on pins and space. One of the pins is a common. </p><p>With the popularization of <a href="/wiki/Surface-mount_technology" title="Surface-mount technology">surface-mount technology</a>, 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. </p> <ul class="gallery mw-gallery-traditional"> <li class="gallerybox" style="width: 155px"> <div class="thumb" style="width: 150px;
