ABSTRACT:
A control device (timer) enabling activation of electric appliances for a required time period at Saturday and Holyday within the frame of Jewish religious law is disclosed. The timer comprises a first timing device, activating the appliance from time to time for a short period, and then deactivating it, and a second timing device, which, when activated manually or at any other way, delays the appliance deactivation by the first timing device for a required time period, and so makes the appliance usable for this period, beginning from the nearest initiation thereof by the first timing device. The timer can be a stand alone device or built into the appliance.
