Abstract: Automatic aerosol spray apparatus which contains an aerosol container with a mechanically actuated spray valve, includes a drive motor for driving a mechanism which actuates the valve at regular intervals each initiated by a relatively brief motor drive cycle during which the motor is energized fist through a timer circuit and then through a motor drive switch is improved by light actuated testing apparatus integrated therewith. The testing apparatus includes a light actuated photocell which produces an electrical output for controlling a test switch electrically connected in parallel with the motor drive switch so that the spray apparatus is tested by illuminating the photocell causing the motor to drive through a cycle and actuate the aerosol spray. In a preferred embodiment, the apparatus is energized by a battery and a battery test circuit is connected to the battery and also to a battery test indicator which is activated by the test switch.
