Abstract
A virtual touch screen switch includes a push window disposed over a display assembly. The transparent push window functions similar to a toggle switch, while enabling touch screen functionality. In a preferred arrangement, the push window is disposed in a display opening of an electronic apparatus and is pivotable between a neutral position and one or more actuating positions where an actuator mounted to the push window actuates a PCB switch. With this arrangement, function keys from the electronic apparatus can be eliminated with a toggle-type switch arrangement, thereby reducing the apparatus size while maintaining reasonable manufacturing costs.
