A simple electrical timer switch control for consumer users is described. It provides automatic time control of outdoor appliances such as lawn sprinklers. A simple, novel, and unique hermetically sealed outdoor casing provides protection from electrical shock hazzard while maintaining the portable characteristics of the control. Means are provided for selecting any one, or more, time interval(s) in any given 24 hour time period; and, for automatically overriding the selected time interval(s) within any 24 hour period, or combination of 24 hour periods, within any given 14 day period.
