Nomenclature
Operation Key
The dedicated key prevents operational mistakes and forci-
bly separates the contacts.
Head
The head can be mounted in four directions. The Opera-
tion Key can be inserted in five directions including the
downward direction.
Cover
The cover, with a hinge on its lower part, can be opened
by removing the screw of the cover, which ensures ease
of maintenance and wiring.
Built-in Switch
Has a positive opening mechanism which forcibly separates
the NC contacts even if they are welded.
The built-in switch incorporates a pair each of NC contacts
and NO contacts or two pairs of NC contacts.
Conduit
Wide switch variations.

Oil Seal
The plunger has an O ring. The switch casing ensures
IP65 (except the keyhole, which ensures IP00). Use the
D4DS in places where the keyhole is free from oil and
metal chips.
Note:
The housing and head of the D4DS are made of synthetic resin. If high
mechanical durability is required, use the D4BS Safety Door Switch.
