Abstract
A touch sensitive switch with a light comprises a light sensor which detects a finger approaching the key top using the output of the light sensor to detect that the touch sensitive switch with a light is to be operated before the operation takes place. Notification to the person who operates the key-top can therefore be given by any predetermined effect such as a voice accruing based on the output of the light sensor just before the operation starts. Therefore, confusion does not arise even when the switch is put to a large number of uses.
