Note: 1.
Pay attention to the polarity of each LED. The anode and cathode can be identified by finding the cathode mark, as indicated on the Dimensions page.
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)=
(Voltage used (E) – LED forward voltage (VF))
