Abstract
An illuminated control button with an eccentric switch and a button spring configured to substantially balance the mechanical resistance of the switch when the button is depressed. The switch may be a conventional push-button switch having a stem directly contacting a portion of the control button. The button spring may include an integral reflector and may have a rim that defines a surface engaging the button. The control button may include a fixed light source and the reflector may move about the light source when the control button is depressed. The present invention also provides a control button with a light source at least partially contained within an integrating sphere. In one embodiment, the integrating sphere includes a somewhat cup-shaped diffusely reflective surface that cooperates with a diffusely reflective surface on the back surface of the button to substantially evenly distribute light from the light source throughout the integrating sphere.
