The detent lever is indexed relative to the internal mode switch. A spring assembly is in engagement with the detent lever. The spring assembly has a first member that engages the internal mode switch to prevent the internal mode switch from rotating and has a second member that engages the internal mode switch to prevent the internal mode switch from rotating if the first member does not engage the internal mode switch.
