Default Light switch 3 pole and 2 pole

Please help. I just installed two 2 pole light switches in the bedroom
(they should have been 3 pole). When I went to turn on the power it
tripped a breaker so I knew it was not right. I looked online and
found I should have bought two 3 pole switches, so I went to HD and got
2 of them. Now they are both installed, but I am unable to turn on the
light. When I tested with a multimeter I found only one switch has
power going to it while the other has none. Anyone have a clue what
happened? Did I 'fry' the wires? What do I do now?


I agree with all that Jeff says.

FTR, they are called 2-way and 3-way, terms of art, used only in 110
volt electricity**, afaik.. None except 4-way is more than one pole.

**And maybe in Europe they use the same terms with 220 volt
electricity. I don't know about Africa and Asia!

2-way is single-pole, single throw, and
3-way is single-pole, double-throw.
4-way is double-pole, double-throw, and it is assemble so the two
throws reverse the poles. But you're not quite ready for 4-way yet.
