Original Question
Can anyone recommend a rotary switch, transistors, Ic's, or any
component that may work for following situation?
I have a circuit 4.5 vdc and three momentary switches in series (two
mercury and one 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(s) possible. I
have
minimal experience with the different type of components, but have
time and a willingness to learn.

This was a reply that I received in regards to my original question
avove. The problem is I;m not quite sure how to set the circuit up.
Can anyone show it on a schematic? Is there a easyer or better way? If
so, can you put it into a schematic? Thank you for your time

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.

Momentary switches are just that, doing the work as long as you provide
the "momentary" activation. So what you want to accomplish you need
instructions from flute playing teacher who will teach you how to place
your fingers on them.;^)
For any other solutions you need memory to keep information that a
switch is now active and is part of the cirquit. ( The toggle's solution
looks like right idea).
You have conflictic requirements, any single switch can do the work of
all of them so why this redundancy?
Define better the logic of what you need, will be easier to solve.

Put a toggle switch in parallel with each momentary
switch. To disable the action of any one momentary
switch, close its paired toggle switch.

Stanislaw,

The entire original question. Can anyone recommend a rotary switch,
transistors, Ic's, or any component that may work for the following
situation? I have three momentary switches in series (two mercury and
one reed). What I would like to do is to be able to have the ability
to allow anyone switch work alone, any combination to allow 2 to work

components, but have time and a willingness to learn.

I will give you the benefit of doubt. You probably didn't get the
entire original question that I asked. If you did I'm sure you would
have answered it differently. Either way answering a question in this
way;

"So what you want to accomplish you need instructions from flute
playing teacher who will teach you how to place your fingers on
them.;^) For any other solutions you need memory to keep information
that a switch is now active and is part of the cirquit."

Would surely deter any new beginners in the world of electronics, that
has so much to offer. Hope you can understand where I'm coming from.

In my mind I have a picture of something that decides in advance which
of the possible combinations will perform the activation of the load.
a) any single switch (which one?)
b) two in series a&b; a&c; b&c (chosen in advance)
c) all three at once.
So you need a selector to configure/chose the working team from all
those possibilities. I simple cannot imagine a circuit that will display
those changing variations without external intervention.
In electronics everything is possible, miracles take a little longer, so
even to beginner we advise to define the performance of the finished
product and "I want" is not a factor in this.

Have fun

Stanislaw.

Stanislaw,

A mi didn't take to long for this gentelmen to come up with the
correct answer, on his first try, with no further explanation. He was
able to answer it from my original post even though the words "I want"
were in my post.

Below is the answer I was looking for:

Here's how I would do it, provided my diagram below
accurately captures what you want:

+ ---Sw1---Sw2---Sw3---Load--- Gnd "All Three"


+ ---Sw1---Sw2---------Load--- Gnd "Any Two"
+ ---Sw1---------Sw3---Load--- Gnd "Any Two"
+ ---------Sw2---Sw3---Load--- Gnd "Any Two"


+ ---Sw1---------------Load--- Gnd "Any One"
+ ---------Sw2---------Load--- Gnd "Any One"
+ ---------------Sw3---Load--- Gnd "Any One"


Assuming the seven possibilities above are what you
want, you could wire it this way, with a toggle switch in
parallel with each momentary switch:


/ / /
+--o o--+ +--o o--+ +--o o--+
| Tsw1 | | Tsw2 | | Tsw3 |
| | | | | |
+ ---+---Sw1--+---+---Sw2--+---+---Sw3--+---Load--- Gnd


That way, any momentary switch can be removed from affecting
circuit function and replaced by a connection to the next.
3 minature toggle switches will take up a lot less space
than 2 rotary switches.


By the way, the diagrams are shown using DC, but it will
work fine with AC or DC.

I'm sorry I did not get back to you when you first replied to my post.
My post was answered shortly after. I should have let you know. I do
value your replies and belive you have answered my posts in the past.

The moment you mention 'toggle' you incorporate mechanical memory into
the circuit and it needs to be set in advance. In your description of "I
want" somehow this part was _very_ weak.

Good luck

Stanislaw.
