Circuitry task

The following task is proposed, which seemed very interesting to me.

Unfortunately, the thematic blog “Entertaining Tasks ” is closed and
Khabaruzers will have to connect to leave comments and find out a solution , but this one-time operation will not take much time.

It is required to connect a voltage source, three buttons with normally open and normally closed contacts, three lamps and a loudspeaker so that when you press the first button, the loudspeaker roars and only the first lamp shines, when you press the second button, the loudspeaker roars and only the second shines lamp, when you press the third button, the loudspeaker roared and only the third lamp glowed. UPDwhen the buttons are not pressed, none of the lamps should light up and the speaker should not roar.



The rated voltage of all equipment is ~ 220 V. The loudspeaker will burst only if 220 V is supplied to it, the lamp will light up only if 220 V is supplied to it.
