Claim 0:
1. A drive system for driving a switch, the drive system comprising:
a drive shaft configured to connect the drive system to the switch;
a motor having a motor shaft, the motor shaft configured to drive the drive shaft;
a feedback system, the feedback system comprising an incremental encoder and a microswitch, which in combination are configured and arranged to:
detect an absolute position of the drive shaft or an absolute position of a further shaft connected to the drive shaft; and
generate at least one first output signal based on the detected absolute position of the drive shaft or the detected absolute position of the further shaft, and

the feedback system being configured to:
determine at least one value for the absolute position of the drive shaft based on the at least one first output signal; and
generate a feedback signal based on the at least one value for the absolute position of the drive shaft; and

a controller configured to act on an operation of the motor based on the feedback signal,
wherein the microswitch is directly attached to the drive shaft, and
wherein the incremental encoder is directly attached to the motor shaft.
