Abstract: A circuit module for synchronizing the driving of an electrical device module with a second electrical device of a second circuit module is provided. The module includes the electrical device designed to assume a first and a second state, a control unit for controlling the electrical device, wherein the control unit is designed to provide a control signal, depending on which control signal the electrical device changes from the first state to the second state, and a trigger line coupled to the control unit, via which the control unit is couplable to the second control unit of the second circuit module. A synchronization signal is providable at the second control unit by the control unit via the trigger line, which synchronization signal is correlated with the control signal for initiating at least one change of the electrical device from the first to the second state.
