Abstract
A multimode key system provides a multiple of keys for multimode control, wherein only desired function keys are shown on the control panel at a time, and whereby the operation thereof can be much simplified. The key system can be a touch panel or a pressure sensing panel, which characterized in a shifting unit integrated with an outer shell. The shifting unit can shift the a printed keyboard or a keyboard display grid board, so that the windows on the grid board display a set of corresponding keys on the printed keyboard, and thereby a user can see and touch the keys to operate a corresponding appliance or an industrial device.
