● Refer to the "Common Precautions for Pushbutton
Switches/Indicators" for common precautions.
● Mounting multiple PCB Terminal Pushbutton Switches
Be careful with the pitch between the centers of mounting holes
when mounting multiple PCB Terminal Pushbutton Switches,
otherwise the Switches may be , resulting in malfunction.

Note:  Make sure the thickness of the mounting panel is between 0.5 and 3.2
mm. If, however, a Switch Guard or Dust Cover is used, the thickness
of the mounting panel must be between 0.5 and 2 mm.
 If the panel is to be finished with coating, etc., make sure that the
panel meets the specified dimensions after coating.
