Flush actuator styles offer non-illuminated, bi-color ring or dot illumination or the International Standby symbol. Mushroom style actuators are also available in red anodized aluminum. Illumination color choices are red, yellow, green, blue, white and orange. LED voltage choices range from 6V to 220V.
