Abstract
A key cap and switch are provided for an electronic keyboard apparatus such as an electronic typewriter, a computer, or other data input apparatus. A torque rod is provided which is mounted pivotally directly on the switch and interconnects by sliding and pivoting connection with opposite ends of the key top, and thus to prevent tipping of the key top if an off center depressing force is applied thereto. Since the torque rod is mounted on the switch and interconnects with the key top it can be preassembled with these parts and need not be assembled with the switch mounting panel or any other fixed parts of the apparatus.
