# What Switch or Component Will Work?

Can anyone recommend a rotary switch, transistors, Ic's, or any
component that may work for following situation?

I have three momentary switches in series (two mercury and on reed).
What I would like to do is to be able to have the ability to allow any
one switch work alone, any combination to allow 2 to work in series,
and all three to work in series as they are now? II have limited space
and would like to use the lowest profile component possible. I have
minimal experience with the different type of components, but have
time and a willingness to learn.

Thank You for Your Time Tom,

DK

It might do it, so I've put a drawing "Combi-switch.png" on the A.B.S.E

Use three toggle or slide switches, one across each existing
switches. Turn a switch on to disable the one(s) you don't want to use.

use a 2 pole rotary switch to give you the combinations, and use diodes
for the selection of any 2 switches or any one.. or all in series.
basically, just tie them all in series.. and use diodes to select
the pairs.
THe diode will prevent back feed to other combinations.
The circuit will have to be DC.

Any more home work questions?

What if the circuit is AC? How about snubbers to protect your
diodes?

parrallel each switch with a normal switch.
turning that switch takes it's parnmer out of the equation,

Thank you for getting back to me so soon.
You asked if I have anymore home work question, well you've got it.

I can work off a schematic very easily. Once I've built a circuit and
understand how the components work together, I can then make up my own
circuits involving those components. Each time I put together a
circuit I document it and use it as reference to build a new circuit.
I know this is real basic but if I had a schematic it would get me
type of circuit, I think? So if you really want some more home work I
would surely appreciate it if you could come up with a schematic using
your recommendation on how I should be done.

Thanks Again for Your Help
