It has a key switch that enables or disables opening of the shutter. There are also switches for turning deuterium source and tungsten-halogen source on and off; each switch is used independently.  The timer on the front panel can be used for recording the total operating time for deuterium source. There is also a controller that would be able to adjust the light intensity of tungsten-halogen source.
