Disclosed is a wall-mountable display apparatus that is simple in structure and excellent in withstand load. According to the invention, the magnet armature of the solenoid actuator is an axially guided annular magnet armature, and the means for power transmission are arranged coaxially around the axis of travel of the annular magnet armature. As each instruction is considered for addition to a group of instructions for a single cycle, dependencies are checked to determine whether the entire group can be scheduled in any possible order. The switch drive turns on the bypass switch device to at least partially bypass the current limiting device as a voltage level of an input of a switching converter rises.
