ABSTRACT:
A large area button in an electrical keyboard is prevented from jamming by being stabilized against tilt which results from depressive forces being applied remotely from the center of the button, the stabilization being achieved by the provision of two anti-roll bars attaching the button to the body of the keyboard and each preventing deviation of one of two axes of the button from being orthogonal both to one another and to the direction of depression of the button.
