Abstract
A keyboard includes a body having a number of depressions formed in the upper portion for collecting water, a-number of channels extend upward from the depression for slidably receiving buttons. A base is secured to bottom of the body and a casing is secured to bottom of the base. A number of conduits extend downward from the depression for communicating the depressions with the casing for allowing water collected in the depressions to flow into the casing so as to prevent water from flowing into the circuit board received between the body and the base.
