Note:

MBB (Make Before Break) contacts have an overlapping structure, so that before the normally closed contact (NC) opens, the normally open

Operation 
key hole

Head
The head can be mounted 
in four directions.  

Sealing properties
The switch casing ensures IP67 
(except the keyhole, which 
ensures IP00). Use the D4NS in 
places where the keyhole is free 
from oil, water, and metal chips.
