Is There Such a Switch That...

I have a dilemma comming across a project i want to tackle. Basically, one of the things i need it to do is have ONE switch that controls 3 inputs to 3 outputs. Basically, i want it that so when switch is on, input 1 outputs to output 1, input 2 outputs to output 2, and output 3 outputs to output 3. May be kinda confusing, but if there is, please notify me! I was thinking it would be a switch with 6 prongs, 3 for inputs, 3 for outputs, but i didnt know.

Thanks

That would be a "Three Pole Single Throw" (3PST) switch. Alternatively you can use a Three Pole Double Throw (3PDT) switch and only use 6 of the 9 terminals.

Yes there are switches like that, and/or you can compose such switches too.

If you need a more fitting answer, you should supply more information like:

  • What kind of signals you want to switch
  • What size of switch is acceptable
  • How do you want to control the swicth

And anything else that might shed some insight in what you want.

Okay! Thanks alot for your..very appreciated knowledge! :slight_smile:

And for this question, i just needed a basic yes or no answer so i didnt think i needed much info. But when i do need more of an answer, ill be sure to add alot more info!

Well, it seems i do need to add more info because i cant seem to find a good one. Im only finding like double throws, which said i could use, but i rather have just what i need and not more.

Im doing this sort of project so it would have 12V DC at 2A-4A. Just a simple switch for controlling 3 separate inputs at the same time.

Thanks

You can use 1 switch connected to the grids of 3 transistors. Each will have its own flow.
Transistors running fully opened are switches.

DigiKey.com has several 3PST toggle switches. Most are from NKK. This one is cheapest:

Transistors with grids. Someone thinking of the good old days ?

Someone has trouble remembering terms he doesn't use often. What's the word? Is it base? Oh yeah, base, collector, emitter.

But with resistors and transistors 1 pin or switch can turn many on/off affordably and reliably.
