Door Interlock Switch
D2T
Compact DPST-NO Snap Action Switch
Incorporates circuits for power and low-level loads
Approved by safety standards, such as UL, CSA, and VDE
As compact as OMRON's V-series snap action switches
Contact gap of 0.7 mm min.
Panel or screw-mounted with ease
Straight and angled terminals are available
RoHS Compliant
Ordering Information
Actuator Right-angled solder terminal Straight solder terminal
Pin plunger D2T-T1 D2T-T1S
Hinge lever D2T-LT1 D2T-LT1S
Note: The actuator of the D2T is identical to that used for OMRON's V-series Snap-action Switches. The actuator can be replaced with other types
of actuators. Contact your OMRON representative for details.

Micro load
When mounting on a metal surface, be sure to provide a separator
between the switch and mounting plate.
Power load
Note: The circuit switching power load has a snap-action mechanism.
The circuit switching low-level load has a slow-action mecha-
nism.
