Ultra Subminiature Basic Switch
D2MQ
Superminiaturized Basic Switch with
Angle-terminal Models
Miniature size (6.5 x 8.2 x 2.7 mm) and weight as
light as 0.3 g contribute to miniaturization of
devices.
PCB mounting and angle terminals for side
operation are available.
Excels in electric characteristics with the snap-action mechanism despite superminiaturized design.
Gold-plated (Au-P) contacts for micro load
switching available in addition to the standard
silver-plated contacts (Ag-P).
Ideal for applications where size and weight
requirements are crucial, such as in electronic
wristwatches and miniaturized optical and audio
equipment.

Correct Use
Mounting Dimensions
Refer to pages 22 to 29 for common precautions.
Use M1.4 mounting screws with screws to mount the Switch. Tighten the screws to a torque of 0.1 N S m {1 kgf S cm}.

Note:
Terminal gap: 1 pitch
Terminal Connections
When soldering a lead wire to a terminal of the D2MQ, use a soldering iron with a maximum capacity of 15 W maximum (iron tip temperature: 250° max.) with the actuator at the free position and do not
take more than 3 s to solder the lead wire, otherwise the characteristics of the Switch may change.
Applying a soldering iron for too long a time or using one that is rated
at more than 15 W may degrade the Switch characteristics.
Do not apply a force more than two times the rated operating force to
the actuator and leaf lever.
Make sure that the actuator is not hindered by any object from moving to or beyond the rated overtravel.
Do not change the operating position by modifying the actuator.
Do not use the Switch in an application where the operating speed is
extremely slow or the actuator is set in the midpoint between the
free position and operating position.
Install the pin plunger switch so that the operating force is applied in
alignment with the stroke of the actuator.
Do not apply a shock to the actuator, otherwise, the Switch may be
damaged.
Do not apply excessive force to the actuator of the Leaf Lever
Switch in the operating, releasing, and horizontal directions.
Separator
When mounting the Switch on a metallic surface, be sure to provide
a Separator between the Switch and mounting plate.
The Separator must be made of hard material and must be processed as shown below.
