Abstract
A controller of a rotary switch receives, via a contact receiver, signals from a plurality of fixed contacts of a rotary switch that rotates a movable contact to connect the movable contact to any of the fixed contacts, and outputs a command based on the received signals. The controller of the rotary switch monitors a transition of an output code received from the contact receiver, and determines that a failure has occurred in the rotary switch when the transition of the output code does not match a transition pattern of the output code of the case where the rotary switch operates normally.
