Note: 1. There are five colored caps or a transparent cap for Switches with single-color LEDs. There are milky white or transparent caps
for Switches with two-color LEDs (combination of different-color LEDs).
2. For Switches with two LEDs, red and green, the red and green LEDs illuminated simultaneously become orange for use as a
three-color LED. Use a milky white cap in this case.

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.

Precautions
Be sure to read the safety precautions common to all Tactile Switches on pages for correct use.
LED
Switches with high-brightness green (HG) or blue (B) LEDs are
susceptible to static electricity. Be careful when handling a Switch
with these LEDs as it may cause the Switch to breakdown.
Removing the Cap
1. Hold the cap at the side away from the mating section. Pull
straight up.
2. Do not remove the cap while the Switch is mounted. Doing
so will apply force to the soldered section and LEDs, result-
ing in malfunction.
Placing the Cap on the Switch
Hold the Cap at the side away from the mating section. Push
straight down until the mating section meets.
Removing the Cap
The Cap can be removed up to two times. Excessively removing
the Cap will cause the mating section to become weak, resulting
the operating section not mating completely or the Cap may loos-
ened out.
Film Dimensions
Dimensions of the film are shown below. The thickness is 0.2 mm.
