Abstract: A transmitter comprises a housing, an electronics assembly, an inner cover, and an outer cover. The electronics assembly includes an actuatable switch and fits within an open-ended cavity in the housing. The inner cover is positionable over the open end to cover the electronics assembly and has a deflectable button portion which is alignable with the actuatable switch and accessable from the open end while the electronics assembly is energized. The inner cover is electrically conductive and has a sleeve which frictionally mates with electrically conductive walls of the housing to shield the electronics assembly from electromagnetic interference (EMI). The inner cover is preferably an insulating molded plastic part with a thin metallic coating.
