1. ※The minimum packing unit means the basic unit of order. Place your purchase order in N minimum package units （N: integer）. Ask us for the export packaging unit.
2. For SKQUAA, and SKQUBA models, the 4-directional operating force and travel are measured 0.9mm below the top
of the stem.
3. For SKQUCA models, the 4-directional operating force and travel are measured 2.9mm below the top of the stem.
4. For SKQUDB models, the 4-directional operating force and travel are measured 1.5mm below the top of the stem.

4-directional with Center Push
(SMD & Snap-in) Type
SKQU
Series
Compact 10mm square type provides compound actions of 4-directional and center push.
A sharp click feel with tactile feedback characteristic.
The stem has a joint shape which allows a knob to be attached on.
Two types are available: snap-in type allowing automatic flow
soldering. SMD type allowing reflow soldering.
Surface mount type products are packaged with a 32mm width
embossed taping.

Example of Reflow Soldering Condition
1. Heating method: Double heating method with infrared heater.
2. Temperature measurement: Thermocouple 0.1 to 0.2
φ CA（K）or CC（T）at soldering portion（copper foil surface）. A heat resisting tape
should be used for fixed measurement.

1. The condition mentioned above is the temperature on the mounting surface of a PC board. There are cases where
the PC board's temperature greatly differs from that of the switch, depending on the PC board's material, size, thickness, etc. The above-stated conditions shall also apply to switch surface temperatures.
2. Soldering conditions differ depending on reflow soldering machines. You are requested to verify the soldering
conditions thoroughly beforehand.
