Note:
1.
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 with the OMRON mark.
2.
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.
Limiting resistance (R)=
