Abstract
This disclosure describes systems, devices, apparatuses, and methods of retracting or extending a button, such as a depressible button, pad, joystick, trigger, or bumper. The button can include a movable structure with magnets at two positions and a coil that can be energized to create a magnetic field. The button can be configured to retract when a current is applied to the coil, and to extend when a different current is applied to the coil. The button can include a magnetic core that can latch to a magnet when the button is retracted and that can latch to a different magnet when the button is extended. In some configurations, the button is configured to retract or extend relative to a printed circuit board, a housing, or both.
