The American Range A10003 Door Switch is a 15 AMP electrical switching component used in compatible commercial cooking equipment. It responds to door movement to control an associated electrical circuit, supporting equipment functions that depend on the door position. This switch is suitable for service when an existing door switch becomes worn, damaged, or fails to operate correctly. It can be used in restaurants, hotels, cafeterias, bakeries, catering facilities, and other commercial kitchens. The 15 AMP rating makes it suitable for specified electrical control applications within compatible range equipment during routine maintenance and servicing.
