Use 8 dpdt 1v relays.All relay coils in series through the N.C.
contacts on each. When one button is pushed it energizes its coil
through a separate circuit with one of it's N.O. contacts with an
appropriate resistor as we're using a 12v battery. The other N.O.
contact operates it's LED and buzzer. Another pushbutton can be used
to reset.

This project is for a �student Quiz Bowl (think Jeopardy). Eight
handheld push button switches that turn on an led indicator (one for
each player) and energize a buzzer. It must also block all other
buttons so there are no simultaneous lights. Oh, and must be battery
powered.

Just to clue you in on my capabilities, the last course I took in
electronics was for tube radios. I can solder.
