A keyboard assembly having a housing with one or more openings in which keys are located. A circuit board is located inside the housing and adjacent said keys such that the keys for causing switches of the circuit board be switched when a user strikes the keys. A liquid resistant barrier is located between the keys and the circuit board and has deformable members disposed to resist movement of the keys. In one keyboard assembly, the liquid resistant barrier is configured and located to direct liquid that has passed through the key openings to a drain channel in the housing of the keyboard assembly. In another keyboard assembly, a seal is defined between the liquid resistant barrier and the housing to prevent liquid that has passed through the key openings from contacting the switches of the circuit board. In another keyboard assembly, the upper side of the housing includes a recess having protrusions that moveably receive the keys. Liquid spilled into the recess is drained away from the keyboard assembly by a drain channel in communication with the recess.
