LEDs (B3J)
Make sure that the polarity of the LEDs is correct. The polarity is
not indicated on the Switch, but the positive pole is located on the
back surface of the Switch on the side without the OMRON mark.
Connect limiting resistors to the LEDs. The Switch does not have
built-in limiting resistors, so satisfy the LED characteristics by
obtaining the limiting resistance according to the following formula
based on the voltage to be used.
