What is the difference between Phase 1 and Phase 2 clones?

Phase I armor was mass-produced for an army bred to fight and die. Phase II armor, even though it was more expensive, offered countless benefits for the Republic. It offered a sense of individuality to each trooper because each suit could be specialized if needed, and it was more comfortable for the wearer.

When did the clones switch sides?

Tiplar was killed when Protocol 66 was prematurely activated within Tup. Towards the end of the war, Order 66 was almost prematurely exposed due to a malfunction in the biochip inside clone trooper CT-5385 “Tup,” resulting in the clone alternating between his regular self and a trance-like state.
