ABSTRACT:
A wall-mountable electrical timer for controlling the delivery of power from an AC power source to an electrical load, such as a lamp or a fan motor, includes: a timer adjustment actuator for selecting a predetermined time period of operation for the load; a toggle actuator for starting the timer, turning off the timer, and placing the timer in a bypass mode of operation; a vertical linear array of light-emitting diode visual indicators for indicating the length of a predetermined time period, the time remaining, and whether the timer is in the bypass mode; a controllably conductive device for regulating the delivery of power from the AC source to the load; and a controller for receiving inputs from the timer adjustment actuator and the toggle actuator, and for transmitting outputs to the visual indicators and the controllably conductive device.
