Abstract
A drive apparatus for an isolator switch includes a motor and a gear mechanism. The gear mechanism has a drive shaft which can be driven in two opposite directions of rotation by the motor and the gear mechanism has an output shaft. A load torque lock prevents transmission of a load torque which acts on the output shaft to the drive shaft in either direction of rotation. An isolator switch with a drive apparatus is also provided.
