DIP Switch Packaging; Switches are supplied in standard IC tubes or tape and reel Note; A top tape seal is required for switches that are machine soldered or heavily cleaned after hand soldering. Tri-State DIP Switch Unfortunately there is another graphic missing, one that shows a tri-state DIP switch. Yes they do make 3-state switches in DIP. Dip Switch Calculator. DMX is a digital control protocol used for lighting control. The control is done by ten switches. Some units will not use the 10th switch. This DMX control is used to find the right dip switch for a certain address setting of a light system that operates in DMX 512 mode.

DMX Address Setting
DMX is a digital control protocol used for lighting control. The control is done by ten switches. Some units will not use the 10th switch. This DMX control is used to find the right dip switch for a certain address setting of a light system that operates in DMX 512 mode.
Dip Switch work in binary. Hence, Switch one represents value 1, switch 2 is 2, 3 is 4 , 4 is 8, 5 is 16, 6 is 32, 7 is 64, 8 is 128, 9 is 256.
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
2^6 = 64
2^7 = 128
2^8 = 256
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
2^6 = 64
2^7 = 128
2^8 = 256
Example
If you want to set DMX address for value 13, the highest numbers that fits 13 is 2^0,2^2,2^3 (1+4+8)
Switch 1 is 1
Switch 4 is 3
Switch 8 is 4
Hence, switches 1,3 and 4 will be set as ON.
Switch 1 is 1
Switch 4 is 3

Hi Carl,
I used the Eagle before I discovered KiCad. The Eagle has dip symbols similar to the proposed once, that's one of the personal reasons I made them like that.

For me, it's similar to connectors. Why don't we use one part with multiple units for them? You would just use the number of units you need and set the right footprint... Same problem.
If I can guess, the most common way of using DIP switches is setting a configuration of something (e.g. microstepping for stepper driver, default behavior of MCU firmware...), in that case, one side is usually tied to some voltage level and the second one is connected to e.g. MCU IO port (like in the example below). In this case it makes sense to keep it in single unit as it makes the schematic more easier to read and it's usually simpler to draw. Could you imagine something similar with the 8 separated switches? It would take much more space on the sheet and it could confuse somebody else looking at it.
Separation into units makes perfect sense for gates and similar parts you connect together in much complicated ways. But for DIP switches I see more disadvantages than advantages...

What do you think?
P.S. It would be great if there was a wiki of things to do for the contributors, I mean something like TODO with packages to fix, parts to add... And maybe some discussion page to talk about similar issues like this one. It could make the kicad library much better and bigger. The quality and size of the library is what matters when deciding which EDA to use.
