RV Ambulance Police Car custom switch laser engraving

Most of the switches in cars and aircrafts are illuminated so they can be seen at night with backlight. Those switches are made with translucent white plastic painted in black, then laser removes paint in areas where art needs to show up.  There are different ways to do back lit illuminated switches but we prefer using fiber laser as it will only affect dark colors. Same method is used for laptop keyboard engravings. Modular back lit switches and tumblers are usually used in ambulances, police cars and RVs
