If the switch will be composed of component parts the housings A ( x 4) and B ( x 2) have to be ordered. Limiting detent to 0 (BCD) is being done with a stop screw M.2 x 2.5. Bottom view: Hollow Shaft System A = B = 2 C = 4 D = 8 BCD Coding Hollow Shaft Available for switches up to 4 wafers; inner shaft (Ø 2 mm) to be ordered separately. 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 maximum of wafers with 4 wipers each. Please indicate type of each switch.
