Abstract (en)
[origin: EP0788995A1] The device has a control circuit which monitors the operative state of a switch and depending on the state generates signals to initiate illumination of the switch. A switch module (11) is provided with the switch (SW1) which is connected to the control circuit by leads, one (17) for sensing the state of the switch and the other (22) providing a release signal. A pulse expanding module (12) prolongs the illumination signal received from the control circuit according to the switch state. An illumination module (13) illuminates the switch for the duration of the prolonged illumination signal.
