BCD Coding
12 positions; the coding will be made according to the opposite layout on the
printed circuit. If the switch will be composed of component parts the housings A
(3 x 4) and B (1 x 12) have to be ordered. Limiting detent to 10 (BCD) is being
done with a stop screw M1.2 x 2.5.
BCD Coding
Hollow Shaft
Available for switches up to 4 wafers; inner shaft (Ø 2 mm) to be ordered sepa-
rately.
Inner Shaft
Must be ordered separately for switches with hollow shaft.
Switch with 2 Drive Shafts
Consisting of a hollow outer plus an inner shaft, the inner shaft driving a maxi-
mum of 3 wafers with 4 wipers each. Please indicate type of each switch.
