A modern simple doorbell button by Luxello is a solid round aluminum casing that is finished in a satin anodized aluminum. The doorbell button housing is made from a spun solid piece of aluminum that conceals the wall mounting screws. The satin doorbell button is available in four LED colors. The Simple satin Doorbell button connects to a standard 8 - 16 Volt AC or DC wired doorbell system. The buttons can also be used as a garage door button. Designed by Luxello, 2010.
