Abstract

A flip-type portable telephone includes means to turn keypad illumination D1-D8 on or off in response to the open or closed position of the flip. There is no delay in turning the illumination off, thus saving power. The flip position sensing means comprises a switch 14 mounted in the body of the telephone operated by a magnet 20 mounted in the flip.
