What part should I replace to change the 24-VDC voltage of the lamp for A16L--24D Push Buttons to 12 VDC?
The Socket Units can be used for both voltages. Simply replace the LED lamp. The model is A16-12DS. (Insert the color symbol in the box.) R: red, G: green, Y: yellow, W: white: A: blue. For blue, however, the suffix is -12DA.
