Touch receptors

Hi
I wonder if anyone could clarify the following...

When Pacinian , Merkel, Ruffini, and Meissner  receptors send a signal
along the associated axon, is it always an Action Potential? 
Presumably a graded flow is not possible since it'd expire before it
reached the sc?
Is there usually/always a 1:1 relationship between receptor and neuron
at the periphery, or can several receptors contribute to the
initiation of an AP?

Where the pacinian corpuscle wraps around a nerve ending, would it be
right to call that a synapse - Is that what it is?

Thanks

Tony
