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

ON further inspection, I've noticed that the center section (like a push-button circuit breaker will depress when power is applied and will pop back out when power is removed. Is this normal operation of the relay? I'm thinking about starting the generator and see if that relay does the same thing.
Yes that is the energized coil pulling the contacts together
quit worrying about voltage rating
You can use a motor contactor rated at 220v
But it must have the correct coil voltage
In this case 120v coil
Many motor contractors used in machinery have 24v coils
You can not use one with a 24v coil
Your replacement must have a 120v coil
If you buy from an RV supplier, likely no problem
If you are searching on line for the best deal
You need to pay attention to the coil voltage and the physical size
Or it may not fit
