I want to make a podium that has two light bulbs and two switches, the idea is to make a game-show like stand where two people can come up, be asked a question then the first person to answer hits his respective button which turns on his light.

This is where I need the electrical help, I want to know how I can turn off the opponents light so that the first person to hit their button turns on their light and cuts off the circuit of the other so that only one light can be on at any given time.

Any ideas?

Darn. I was hoping someone would post how to do it.:furious: I've been sittin here lurking so I could have something to do over Thanksgiving when my nieces come to visit. I don't want to order no stinkin' kit!:no: Some one post how to do it with romex and other **** I have in my basement!:laughing: :yes:

Stubbie i did found the curpit why the digram will not work [ sorry i did not get a chance to reply more ealier but i was waiting if other did reply or not ]


but i will tell you in a min actally a error there allready

merci , Marc

give me a few min i will go over the chart very carefully because you marked NC concats it kind threw me a bit

I was temping to draw a digram here but little diffrent but work very simuair that i will use the SPDT relay both with NO conacats each side until that perosn on one side hit it and pull the relay to light up that side and other side can not close the relay due the DT format.

Am i makeing sense ??


Merci, Marc

Okay, let me try again...

I'm a complete dumbass that found this site through Google. I'm not completely stupid with math and electronics so don't give up hope that I won't get it, if someone would take the 15 minutes to explain this to the complete retard that I really am, I would be willing to exchange sexual favors.

Deal?

Ok the first diagram is fine, though it doesn't need the switched power NC in the relays. It could be either 120v controlled or 12 volt controlled. It doesn't need a holding circuit and you wouldn't want one in terms of simplicity so a diy could build the circuit.. It is a simple single pole toggle 'on' 'off' switch. The first person to turn a switch 'ON' disables his opponents power via the switched power energizing the opponents relay solenoid and opening both NC contacts in the relay. As long as the switch is 'on' his opponents relay has open contacts killing all power to his switch. When he toggles off the opponent will have power back.

So if you don't like that one how about this one......120/24 volt controlled by a DPST switch

Stubbie i like that second plan better than my drawing with SPDT set up.

make it harder for someone else try to overide it.

i dont know if you can add delay feature when someone hit the switch it will lock in that postion for few seconds after someone slam the mushroom head button.

what ya think ??

Merci, Marc

Yes, I think a delay feature would work but it complicates what most DIYers would be comfortable trying to build. I would prefer to use the low voltage control of the second schematic over the first one I posted. Either could be easily built at home for about 50 bucks. If you had the transformers then it's very inexpensive.
