Lockout system

I'm trying to build something for a project. The simplest way I can put it is that I need a switch to turn on a light, while simultaneously disabling the other two switches I have from turning on their respective lights. If one is on, the others can't do anything, and I need a reset switch to put the entire system back to the starting point of everything being off.

I'd like to draw a diagram and plan everything out before I buy materials, but I'm completely new to this site and it's tools, as well as not being particularly familiar with all things electronic.

Any help is appreciated, thanks!

For DC at low voltage? Try using an MCU (Arduino or similar) where some of its I/O pins will control the gate of a NMOS which, in turn, each pair I/O pin NMOS will be used as a low side switch for the LED. It is then easy to program the MCU to behave as we want, without having to change the hard-wired circuit.

I don't suggest that you start electronically by "playing" with AC from a household distribution system.
