Help, cannot find answer on internet. I am running 15a 14/2g wire to one light switch from service, from that first switch, I am running 14/3 wire to 2nd switch in order to operate 1 light from 2 sources. I want to add another switch (3rd) to the second switch in order to operate another independent light. Is it possible to tap the 3rd switch into the 2nd switch for a source of electricity? And do I need 3 way switches to do this? How would this be wired if able to do so?
