Zusammenfassung:The control apparatus operates on the phase-shift control principle, and consists of an electronic switch, such as a thyristor or a triac, and a phase shifter which comprises, in addition to a resistor, capacitor and a triggering diode, a potentiometer for setting the switch ignition instant. It is operated from outside, while all the other components of the brightness control apparatus are mounted in a case. the operting element (16) of the potentiometer is in the form of inserting shaft (19) with a rotary knob (21). The shaft can be latched in a retaining member (14) in one piece with the housing (8). The retaining member is preferably a sleeve with inner diameter mating the shaft cross section.
