2-way switch lamp

I see you haven't posted many circuits and great if this is what you wanted and ignore the rest of my babblings following below. Not sure if you wanted a two-way circuit that you turn the light on and off from two locations, like the ends of a room. Single pole, double throw (SPDT) switches are used. Flipping one switch connects or disconnects the voltage source from the lamp, whether the other switch is off or on. If this is what you were looking for just add another switch the other side of the light exactly wired like the bottom switch. Search TWO WAY for others circuits similar to yours or the Examples section.
