Abstract: A rapid assembly electronic device includes a housing and a chassis which snap together and are movable relative to one another between a closed position and a position in which a battery compartment on the chassis is accessible from the outside. The chassis is separable from the housing by the use of a pointed tool. A resilient clip is received in a receptacle on the housing, the clip being held in place by resilient engagement with the housing in three ways. The electronic device is operated from the exterior by a resilient element mounted in an opening in the housing and without a physical connection between the resilient element and any parts which are movable with the chassis.
