How can I replace the LED lamp for A22E Emergency Stop Switch with LED illumination?
Replacing the LED lamp from the Socket Unit
Remove the lock lever and separate the Operation Unit and the Socket Unit. Grip the LED lamp with your fingers, and then rotate the lamp while pressing it into the Socket Unit.

Move the lever in the direction indicated by the arrow in the following figure, and then pull the Operation Unit or the Socket Unit. The lever has a hole with an inside diameter of 6.5 mm, so the lever can be moved in the specified direction by inserting a screwdriver into the hole and then moving the screwdriver.
2. Grip the LED lamp with your fingers, and then rotate the LED lamp while pressing it into the Socket Unit.
Replacing the LED Lamp from the Panel Surface
Using the Tightening Wrench (A22Z-3905), separate the cap from the Operation Unit. Use the Lamp Extractor (A22Z-3901) to replace the LED lamp.
Follow the steps 1 and 2 below.
