Hi, everyone!
I'm new to the forum, and an amateur when it comes to circuit design, but I understand the basics. I would appreciate any help you can provide me with "mess on the floor" that my wife is trying to get me to finish!
Here is the setup. I am trying to build a game show type setup with 4 stations. When a contestant pushes their button, I want the circuit to lockout the others from chiming in. I am currently using 4 DPDT relays that share a common connection that feeds their button using the NC connection on 1 side of each relay. When the contestant hits their button, I want the relay to latch for that contestant, breaking the NC connection for the others so they cannot chime in. I put the circuit in the CircuitLogix and it runs correctly but when I built the circuit, my relays do not latch. Instead they "buzz".
I assume the problem is that the relay is bouncing or the fact that the NC contact is being broken before the NO latch feed to the relay can be made. Here is a sketch of my circuit: Game Show Buzzer
Since I already have all of the components, I am trying to find a way to work with what I have, or make minor alterations (and low cost) to the design to make it work. I'm not sure how to proceed. Should I use a CR setup to sustain the secondary power to the relay once the button is pressed to allow it time make the new NO connection or is there another route I should be pursuing? I should mention that because this is for purely entertainment purposes, I am not concerned with occasional errors.
I appreciate your help!
Thanks,
Sean
