Secret Keeper

Hi everyone..I noticed something unusual in PoA...Sirius said that 
the Potters had switched their Secret-Keeper at the last minute...we 
were led to assume that they did this because Sirius was an easy 
target for Voldemort (it was well known that he was close to 
James)...but, Dumbledore later told Hermione and Harry that he had 
testified to the Ministry that Black had been the Potters' Secret 
Keeper (during that frantic conversation in the hospital wing). 
Dumbledore DID NOT KNOW about the switch. Why would the Potters keep 
something so big a secret from him unless they suspected that he was 
not as good as he seemed? Why didn't they use him as their secret 
keeper? I wonder whether the switch was because of the threat of 
Voldemort or Dumbledore. Sorry if this has been discussed already. 
I'd love to hear your responses anyway.
