How to read this switch data
Each switch position is represented by a vertical line.
Contacts are arranged horizontally.
Contact closure is indicated by a black dot.




Figure 1.


Position A: 5 is connected to 6.
Position B: 3 is connected to 4.
Position C: 3 is connected to 4. 1 is connected to 2.


This is rather like a car's ignition + starter switch with 5 - 6 closed in the off position. Turn 90&deg; clockwise for ignition on and a further 30&deg; for starter. When released from the start position it will spring back to ignition position.



Figure 2.


Position A: no contact.
Position B: 5 is connected to 6.
Position C: 3 is connected to 4.
Position D: 3 is connected to 4. 1 is connected to 2.


Note that in this case A and D the switch springs back to the adjacent position.
