Hope someone can help:

I have three lamps(13w compact flourescent. Each driven by its own 12vdc electronic ballast) that I would like to switch on/off(*select only one to be on at a time) using 3 momentary switches(preferably spdt but I can use dpdt). Currenty I am using three SPDT "alternate action(non momentary)" switches with three non-latching relays. Doing it this way, all three lights can be on at the same time if all the switches are pushed in. I dont want it to work that way. I simply want to build a selector with three MOMENTARY switches....ie:

lamps A,B,C

And Switches A,B,C

When pushbutton"A" is pressed, lamp "A" goes on and lamps "B" and "C" should be off.

When pushbutton"B" is pressed, lamp "B" goes on and lamps "A" and "C" should be off.

When pushbutton"C" is pressed, lamp "C" goes on and lamps "A" and "B" should be off.

NOTE: The above "switching sequence" is not in any order...For example I may want to turn on Lamp "B" first..

Simple concept??? It is just a simple lamp selector using momentary switches

I thought about using 2 latching relays but I can't figure out how to make it work??

It would seem that using relays would be the best and most reliable way to do this but I am totally open to ANY designs!

I am also hoping to keep the cost under $150 and of course I really want it to last!

Any sugestions???

Thanks in advance!

PS Im glad I found this website...Alot of great info!

How about a Rotary Switch. Help with Design? -- posted image.

It has a Knob that you just turn to which one you want.

Or do you have to have push buttons and Relays.

You could just get a push selector switch where all 3 switches are interconnected together. Help with Design? -- posted image.

Thanks for the info but, unfortunatley I have to use Pushbuttons... The control panel and circuit board I am using already has 3 NKK pushbuttons that are alternate action(push on/push off) and they are controlling 3 power relays( non-latching) right now...NKK offers the exact same style switch in a Momentary version....which is really what I want to use....

Let me see if I understand.

You want to control 3 lights and only one is allowed to be on at any given time. with 3 push on off switches

SPST

SPDT

DPDT
