Abstract

A housing assembly in which is placed a membrane keyboard is placed between the pressing layer and the base support. Pressing labels and key zones are respectively printed on a surface of the membrane keyboard and on the pressing layer at corresponding locations. An image layer with image features can be further placed between the pressing layer and the membrane keyboard. The housing assembly hence constructed can be fashionable by changing the upper cover and/or image layer, while the membrane keyboard can be further used on leveled working surfaces.
