any 4post-4post designs?

basically I'm looking for a switch to do this:

i guess it can be redrawn as a linear way too. not sure why i was thinking cross like that. but basically i'd like a switch that's independent connections for all four modes so i can get off, 5v, 7v, 12v. such a thing exist? It'd be great to have for my fans for my rad. Figure that's all I need. No need for a rheobus.

Also, I'm imagining I should use the respective grounds for 5v and 12v so this would be nice

I figure one of these switches for choosing speed and another for push/pull/both would help me out a lot in determining what my needs are

I'm betting that something like that exists, check out mouser's catalog (available in pdf). whats wrong with rheostats though? Making your own front panel bus with leds would be a fun little project.


I thought the fad these days was to use fans that didn't need to be adjusted for noise on radiators (ie yate loons, etc).

yeah I think I'm going to settle on a 7v design but still, I guess if I'm making something to run them at 7v, I might as well go all the way and make a multifunction switch

yeah rheobuses are cool but I don't really feel like taking up a drivebay. If I do, I'd want an lcd for rpm and temps so that'd probably be bought premade

Fans don't like to start at 5V and 7V is almost silent. Why not just get a 2 position switch an switch the negative line on the fan from 0V (gnd) to the +5V line for 7V and 12V selection.

that's a good point. 0/7/12 should be all i need. just need to find some nice looking knobs and get an idea of how i'm going to mod my case to put them in
