2 Switches To One Light. It isn't unusual to wire two or more light and switch combinations from the same power source -- in fact, it's common practice. If you are going to install a new one then go for three wire control method.
The switches used in this type of circuit are called "single pole, double throw" (shown as SPDT on the diagram). Now if I wire both inputs into the one output , it's my understanding that as long as one of the swtches is on, so should the light. My idea for a quick fix is that I replace one light switch with just a cover plate and splice the necessary wires together. (I've only just heard about the light switch tamper-cover, but it's too late for that now).
Once I've determined which circuit that a switch or outlet belongs to, I jot.

Instead of turning lights on or off, control a wide range of lighting and create more ambiance in your home by installing a dimmer switch. This is where I am lost. Perhaps when multiway switching was first strating to be used, the light fixture had a separate switch like a common desk lamp or like, in other countries Single pole means it has one common terminal and double throw means the common terminal can be connected to one of two other terminals.
