I got it now. Thank you very much for your helphi QA,
The dashed black line [ now high lighted in Green] indicates that the two switch elements are on the same switch knob.
Look at this image, the 'wiper' of the switch marked with a arrow head, points to the switch contact which has been selected.
A rotary switch is normally drawn as a semi circle of dots, and the wiper as an arrow, use a dashed line to show that the two sections are on the same switch.
OK.?

BTW: Your drawing is incorrect, it shows individual switches.
I know, I’ve corrected them. Thanks for your reply.The resistors R16, R17, R18, R19 is not connected right.
