I have a 4-way switch system with 4 switches that controls the lights in my MBR. Picture shows 2 switches side by side - one is for hallway and one for MBR. There are 4 such switch sets. One of the 4-way switches has lost some spring tension and the switch is a little flaky - it has to be pushed into a specific spot for it to work.
I tried replacing the 4 way switch with a new one and it does not work as expected. Thinking I might have mixed up some wires or maybe the new switch was faulty, I re-installed the old switch and the system works as expected. I had bought 2 of the new switches and I tried both - neither worked as expected. The likelihood of 2 switches being faulty is simply too low. This leads to the question :: Are there different types of 4 way switches ?
I have yet to pull all the other switches to identify the line, load and the 2 traveler switches.
The new switches are :: Eaton 4-way decorator switches.
