I recently changed a timer out in 3 switch "bank". In changing out the timer I accidently touched the Common from the timer to another light switch. It short circuited. Since that time the timer works fine but the other two switches in the "bank" do not work. I have checked the breaker and it DID NOT trip. Di9d I burn something out in the wall? And is there danger of fire. I changed out the switch that was touched by the Common still nothing> Thanks for any help.
