Forgive my ignorance and if this question has been asked before, but I cannot find it asked anywhere else, please read carefully before telling me it has been asked already.
I'm trying to design a system with a row of switches which each have two positions. If all the switches are in the same position, an LED illuminates. If all the switches are in the opposite position, a different LED illuminates. If any one of the switches are not in the same position as the others, no lights illuminate. See image that should clarify this.
What I need to know is what kind of switch I need. I imagine I need one which has four pins on, two pairs that are entirely independant and are part of seperate circuits. When the switch is in the up position, two pins are closed to allow a circuit, and the other two pins are open. When the switch is in the down position, the bottom two pins are closed to allow a circuit and the top two aren't.
... until I realised that wiring this up in series wouldn't work because it wouldn't make a difference to the next switch in the circuit which position the previous switch was in, but maybe I just need someone to explain some clever wiring to make that work.
I hope this isn't too basic a question, and someone can help.
