Implementations relate to control switch position sensing across a rotational joint. In some implementations, a control input device includes a base member and a roll member rotatable about a central axis with respect to the base member in a roll degree of freedom. A switch contact portion is rotatable with the roll member and moveable to multiple positions in a switch degree of freedom. A first sensor element is coupled to and moveable with the switch contact portion and can be a passive element. A base sensor element is coupled to the base member and configured to sense a proximity of the first sensor element to the base sensor element, and to output a signal indicative of a current position of the switch contact portion in the switch degree of freedom independently of a rotational orientation of the roll member in the roll degree of freedom.
