Transfer Switch Contactors
Are the individual contactors inside the transfer switch replaceable? And does a 50 amp system use 220v contactors? Are they difficult to replace? thanks, Ron

Ron,
Contactors have a rrating for both the contacts and the coil.
In your case,the contacts can be 240volts 50amps.
The coil 120 volts most likely.
As stated above some may have D.C. Coil to eliminate humming.
If your switch has only one contactor, it is normally de-energized when connected to shore power and engerized when the generator is running. Any contactor can have both mechanical problems as well as electrical issues.
I think you would be best served to replace the whole switch
