■ Safety Features
Double Spring Mechanism
Two return springs are provided for the pin plunger. Thus, if either of
the springs are broken, this feature will prevent the switch from
malfunctioning or short-circuiting.
(Applicable to D2D-1000 and D2D-3000 models. The D2D-2000
models with pull-on lock is not provided with this feature.)
Direct Contact Opening Mechanism
The insulating ring, identified by
, will positively break the
circuit if a contact weld occurs in the switch. (D2D-1000 models).
Insulating ring
Example of D2D-1000.
The section marked
pushes the movable
contact to apply force in the direction which
separates the movable contact forcibly from the
fixed contact.

Note: 1. NC-OFF: The force applied to the actuator to cause
it to move from the free position to the position at

which the NC contact opens.
2. NO-ON: The force applied to the actuator to cause
it to move from the free position to the position at
which the NO contact closes
