How to wire 2 two-way switches in series to make a 2-way switch system!? Answered
Hey all, my teacher posed this question as extra credit and I've asked quite a few people and no one can figure it out. The problem is: Use two 2-way switches to create a two-way-switch-system. When I say 2-way swithces I mean a switch with two copper screws. Logically, it can't be done as both switches would need to be on for the circuit to work (power the bulb, that is) but a two way switch system means that either switch should be able to turn on the bulb. This can easily be solved using two 3-way switches (one black screw and 2 copper screws) but this problem can only be solved using two 2-way switches, power, and the bulb. I've drawn a bunch of schematics and I've gotten the closes to answering it. So far, the closest thing I've had is to wire the switches in series but the circuit in parallel. The answer to this is something so ludicrous that you just wouldn't do it, but there IS in fact a solution. Please help! Email me at firstname.lastname@example.org (please include pictures if you are able to! I'm uploading a link to a site with all my schematics.
