Motor Operator Motor Operators are designed for electrical operation of air break switches from remote locations. They are available in a wide range of torque, operating speeds, and control voltages. Motor operators may be disconnected for manual operation of the switch during maintenance or emergencies, and for maintenance operation of the motor operator without operating the switch.
