Abstract
A remote function actuator with pressure equalization. A base or enclosure of the actuator (key fob) has one or more openings covered by a breathable waterproof membrane. The opening allows pressure equalization between the inside of the actuator and the outside environment, and the membrane material maintains the enclosure watertight for the electronic system positioned inside the actuator. Positioning the membrane in a recess and/or under a cover member helps protect the membrane from being damaged.
