Abstract:
A compact crown for an electronic device such as an electronic watch, including a set of wipers capable of determining a rotation angle, rotation direction, or rotation speed, is disclosed. The set of wipers is in contact with at least one resistance member at different angular positions around a rotation axis. The crown may have a group of ground taps disposed along the resistance member and a measured signal may vary based on the position of each wiper as it contacts the at least one resistance member. A compact crown may also include capacitive members and capacitive sensors in order to similarly determine rotation angle, rotation direction, or rotation speed.
