Abstract: An electrical component and housing module for an electrical appliance circuit, adapted to be plugged into a conventional wall outlet. The module has a base plate and a recessed cover formed of dielectric material and assembled to define a protective enclosure. The base plate has a relatively small, rectangular opening and the cover has walls including at least two opposed walls with ventilation slots. The base plate also has resilient means that cooperates with the slots to anchor the cover to the base. The electrical circuit component is secured in the enclosure, and is connected to the electrical appliance by a conventional power cord that extends through the cover. A wall-plug-type connector with an insulating body and contact prongs is electrically connected to the circuit component and has its contact prongs extending through the opening in the base plate for insertion into a wall outlet.
