Abstract
Abstract An improved cradle for a handset as for telephone use wherein the top end of the handset is normally held between a flat spring and a springloaded release member. Operation of the release member moves it out of the path of motion of the handset out of the cradle, and allows the flat spring to push the upper end of the handset away for easy removal by the operator.
