ABSTRACT:
The present invention provides an improved timer device for programming pre-selected time periods during which an electrical appliance can be actuated or de-actuated at the selection of the user, or during which the appliance is in a non-operational state. The timer device is particularly adapted for use in conjunction with a television set for providing time periods during which children or other persons may view television at their option, and other time periods during which power to the television is cut-off and the television cannot be viewed. The timer includes a back-up power supply, particularly a battery pack, for maintaining the timer in its operational condition in the event that line power to the electrical appliance is interrupted or otherwise disrupted.
