PURPOSE: To provide a small-sized illumination module capable of being easily controlled by providing contact sensing switch means in electric circuit means and timer means connected to the contact sensing switch means. CONSTITUTION: In case that an object changing an effective capacity of a sensor, such as human fingers, approaches a sensor 40, a frequency of an oscillator 42 changes. This change is sensed by a frequency deviation detector 44, an output of a control circuit turns on an illumination bulb 18, a programmable timer 68 is triggered, the illumination bulb 18 is kept on by a preset period, then is automatically turned off. This circuit is preferably provided with an effective contact timer 50 and a two-second timer 62 as means for requesting the sensor to make contact therewith twice in a restricted period in order to activate the illumination bulb 18. |
