Coincidence- or not?
I had two wall switches fail within a few days of each other.
A heavily-used 40 year old bathroom light switch caused its 20 year old plain vanilla wall fixture with six LED bulbs to strobe-flash when turned on. All bulbs (installed sabot a year ago) flashed. New switch fixed it.
One of two occasionally-used 33 year old three-way switches controlling a ceiling fan in another room also failed- it had to be in the ON position for the fan to turn, Haven't replaced it yet!
Both are Leviton switches and installed by an electrician during original construction. Not aware of any electrical surges- all electronic equipment, etc., working fine.
