US Patent 9620309 Rotary selector switch and related systems and methods

A rotary selector switch prevents accidental rotation to an undesired position. For example, an automobile moving forward at 55 kph may have a rotary selector switch in electrical communication with its transmission. The disclosed switch prevents accidental rotation that would indicate that a REVERSE gear is desired when it is not. Optionally, on override feature may permit users to overpower an otherwise prevented rotation.
