Contents.History 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'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. It was applied for 1974 and was used in 1977 in an Flipper game.

Types 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, 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 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 (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 (2 7) combinations, allowing them to select a standard ASCII character. Eight switches offer 256 (2 8) combinations, which is equivalent to one.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 (3 8) combinations/codes which is much more than a 8 poles binary type offers 256 (2 8) 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. Typically, the device's reads the DIP switches when the device is powered on.With the popularization of, 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 Slide / rocker / piano DIP switches are commonly available in 1 to 12 contacts (positions), though some are available as special order up to 30 contacts (positions). Applications DIP switches were used extensively in architecture of PC to select. Before the advent of cheaper, battery-backed RAM, DIP switches were also often used on 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 as well as on some early. This design, which used up to 12 switches in a group, was used to avoid from other nearby door opener remotes or other devices. Current garage door openers use systems for better security.These types of switches were used on early for early computers to facilitate compatibility with other video standards.

For example, cards allowed for compatibility.After the late 1990s, DIP switches became less common in. Reasons include the trend toward smaller products, the demand for easier configuration through, and the falling price of. 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 to prevent interference; for example, to control a (and its ) that was to a single-. The DIP switches set a different for each / pair, so that multiple units can be installed in different rooms of the same house, or different units of the same apartment building, without unintentionally controlling each other.References.
