● 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 ±.5 and 3.2
mm. If, however, a Switch Guard or Dust Cover is used, the thickness
of the mounting panel must be between ±.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.
