Answer Posted / dharmveer
A dry contact is a contact that does not provide voltage.
For instance, the push-to-talk switch of a microphone,
which just closes a circuit without providing voltage.
A wet contact is a contact that will provide voltage when
closed, like the switch on the wall that activates the 110
VAC outlet to turn a lamp on in a room.
