A pre-injury contact warning device for a front door of an automatic dishwasher or oven, the front door being openable to a generally horizontal very low position above the floor. In one embodiment, the device includes a housing attachable to a surface of the front door. A warning signal emitter sensorially perceptible by a person receives electric power from a miniature storage battery mounted within the housing. An angle-sensitive switch mounted in the housing is operably interconnected between the warning signal emitter and the storage battery. The switch is open and the warning signal emitter off when the front door is closed, while the switch is closed and the warning emitter on when the front door is open. The warning signal emitter, when on, is sufficiently sensorially perceivable to warn or alert the person nearby the dishwasher that the front door is open and to be avoided. Other embodiments are provided which are operatively dependent upon other forms of sensory perception, e.g. sound and touch or feel. This invention may be incorporated at the time of appliance manufacture or as an aftermarket attachment.
