DIP switch
DIP switches ( jokingly called " mice Piano" ), are small switches that are used for example on the motherboard or other circuit boards to make certain basic settings. The abbreviation DIP stands for dual in - line package, so a design with two parallel rows of terminals. Your Pitch usually corresponds to the simple logical blocks each having the same port number in the so-called DIL (dual in-line), hence the name DIL switch is occasionally to read. The grid dimensions are in DIP package 2.54 mm and in "Half- pitch", ie half the grid size 1.27 mm. DIP switches are produced with 1-12 switching units.
The quality of the switch is affected by the spring steel construction, tin or gold plating, and the seal. Specific dip-switches are vibration proof to 20G, such requirements can be found at teller terminals, slot machines and various industrial applications.
The advantage of a DIP switch over jumpers located in the self-contained design. This he can not how jumpers are completely removed from the board and lost. Disadvantage compared to the jumper is the higher price.
When slide switch it is possible to switch to a shift lever a single contact or by a broader shift lever two or more contacts at a time depending on the design.
Depending on the version, the DIP switches can be either a sliding switch (see figure ) or be designed as a kind of lever switch. Structurally, the gearshift are made of a resilient material, or the switching element may be suspended in the contact hooks. When lever switch also switch can be realized, which can be hung between two adjacent, separate contact hooks.
A DIP switch with sliding levers in 1976 was issued as U.S. Patent 4,012,608.
Examples
- With PCs, certain settings such as a SCSI ID or off state can be set.
- When hand-held transmitter of the garage door opener code via DIP switch is set.
- Frequently DIP switch enabled with arcade machines to the stand to change some game settings.
