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.
