Abstract
A switching control button structure is provided for selectively actuating a plurality of resilient dome momentary contact switches. The momentary contact switches are mounted on a support surface and arranged generally about the circumference of a circle. A pivot pin extends from the center of the circle and supports a key adapted to tilt about the pivot pin. The key has wings extending over the switches and is normally upwardly biased by the switches to a neutral, non-switching position so that a switch can be selectively actuated by applying force to the key anywhere along a line extending from the center of the key through a point generally over the switch. The key has a central circular serrated region by which rapid and successive actuation of the switches can be achieved by applying forces on the serrated region in the direction of the selected switches.
