The Alltrux ATX903-1350 Rotary Switch replaces Mack OEM 7787-650882 and is designed as a service replacement for heavy-duty truck electrical and control systems. This rotary switch provides manual multi-position control for vehicle functions such as HVAC controls, lighting, or auxiliary equipment, supporting reliable system operation and consistent performance in fleet and vocational environments.
