1. A wall-mountable load control device for controlling the power delivered to an electrical load from an AC power source, the load control device comprising:
a controllably conductive device adapted to be coupled in series electrical connection between the source and the load for controlling the delivery of power to the load, the controllably conductive device having a control input;
a controller operatively coupled to the control input of the controllably conductive device, the controller operable to control the conductivity of the controllably conductive device, the controller including a timer;
a toggle actuator operatively coupled to the controller;
a timer adjustment actuator operatively coupled to the controller; and
a plurality of visual indicators operatively coupled to the controller;
wherein the controller is operable to:
select a preset timeout period in response to an actuation of the timer adjustment actuator;
cause the visual indicators to display a representation of the preset timeout period;
control the conductivity of the controllably conductive device so as to enable the delivery of power to the load in response to a first actuation of the toggle actuator;
start the timer in response to the first actuation of the toggle actuator, the timer initialized with the preset timeout period; and
control the conductivity of the controllably conductive device so as to prevent the delivery of power to the load when the preset timeout period has elapsed.
