Abstract
Annular knob-on-display (KoD) devices and related apparatuses. An apparatus includes a frame having substantially annular shape, a dome switch, a plurality of actuator members, and a plurality of pivot members. Respective pivot members of the plurality of pivot members secures an actuator member of the plurality of actuator members to the frame and transfers force applied to the actuator member to the dome switch.
Claims23
An apparatus for a knob-on-display device, the apparatus comprising:
- a frame having a substantially annular shape;
- a dome switch;
- a plurality of actuator members;
- and
- a plurality of pivot members integral with the plurality of actuator members and defining fulcrum axes offset from main bodies of the plurality of actuator members and around which the plurality of actuator members rotate, respective pivot members of the plurality of pivot members to secure respective actuator members of the plurality of actuator members to the frame and transfer force applied to an actuator member to the dome switch.
