Are thermal overload switches required for fractional horsepower motors OR can AC toggle switch (1 HP rated) be sufficient??

If a thermal overload is not provided in the switch is thermal overload required to be provided in the equipment?

Thanks
 
Typcially these small motor have integral overload protection. If not then a simple toggle switch will not provide overload protection.
 
You might want to check 430.32(D). Specifics on the installation can make a difference.
There are some cases on not permanently installed motors 1HP and less where the branch circuit protective device can serve as overload
