5 or more pole 5 way selector switch

I know they use some massive rotary gang switches in manufacturing. The problem using them in a guitar is a space issue. Most of the multiple disk switches are custom made for manufacturers. I've seen them as deep as a foot long with dozens of contacts disks and brushes, but all of that stuff is obsolete now except in some higher voltage applications. These kinds of complex switch applications can be much more effectively be handles using relays mounted on a DC control board that's switched by a digital controller that uses a processor chip and interface of some type. Or you could use a matrix switch that scrolls through as many switch positions as needed.

 

None of that would need to be added to a guitar however. In a guitar you simply need to control maybe three pickups and its easy enough to get those pickup combinations using a simple switch or two.

 

I have no idea why you would need 5 poles. I'm guessing you are talking about a rotary switch too. Two disks have staggering possibilities, more then you would even need for most projects. Learning how you can apply a switch is based around the needs, not around the possibilities.

Rotary switches are very difficult to understand for an amateur because you're working on a three dimensional plane. You have to draw up a grid/matrix of all the possible contacts for all the disk contacts between the connectors. Then you can use the X-Y chart to figure how to wire in the possible connections you want to use for a given position.

 

I been an electronic tech for over 45 years and I couldn't begin to explain the possibilities of an unknown switch. I'd have to have it in hand and possible use an ohm meter to figure out all the contact combinations and even then theres all kinds of creative ways you can use jumperd between contact surfaces.

 

Still if its only a 5 way switch, you do have limited options. In comparison to three DPDT switches you could take three pickups and have at least 16 wiring options. Add three more and you can have something like 32 different series, reverse phase, and on off conditions. (maybe less because many settings will be redundant.

 

Again, to give any advice, you first need a plan. What do you want to do, Learn switches? They connect and disconnect electrical contacts. If you want to learn all the combinations, its a futile effort. Unless you have a mind of a genius, why bother memorizing something like that. Its like learning all the possible combinations of a Rubik's Cube. There's some short cuts to that game but that's only a three by three combination. Imagine a Rubik's cube with 5 rows. You don't memorize that stuff or learn it other then the fact you create a matric and use an X/Y graph to find the connections you would need to use.

 

It winds up looking something like these.

This one is a three pole 6 way switch.

This is a simple single pole 5 way. http://uploads.fender.com/news/fender/606/Strat-diagram2.jpg

 

Once you draw up a matric you still need to make all the electrical connections.

Learning to read schematic simplifies the logic in back of the switches.

This is another version of the matrix.

Another way of drawing the schematic.., Think of schematics as road maps. If you know how to use a Key and read a map, you can figure out the road pats the signals take through wires. \

Some of these get really long in length. http://www.electroswitch.com/electroswitchesandrelays/images/icamGroup.jpg

The possibilities of a 4 pole 5 way selector are staggering, if you want to get only 5 configurations. I'm trying to get 10 configurations using a 5 way switch and a 4PDT. I've worked out most of it, but just one more pole would complete it.

What 10 configurations are you trying to get?

 

I have an SG with a 6 position rotary switch. That gives me all possible combinations of two pickups. Then I have a single coil switch on the bridge pickup, for a total of 11 different pickup configurations.

^^^ Yea you wont fit either of those in a guitar. Ones at least 2 1/2" and the other looks like its 4~6" long.

 

The disks can have two sides but the contacts may or may not be separate for each side. I'm supposing 2 and 1/2 two sided disks would be considered a 5 poles switch. I don't think that make 2 1/2 (they cold but it would be a custom build) so you would have to use 3 two sided disks.

Guitars rarely have room for more then a double disk even when its a miniature rotary.

The S1 system used on some strats has a four pole five-way selector switch along with a 4PDT push-push switch on the volume pot and they fit easily in a stratocaster guitar.

 

What would you have to leave out if you only have a four pole selector switch?
