RadioRA® 2 Hybrid keypad function as a dimmer and keypad combined into a single device. Hybrid Keypads are great for retro-fit applications since they eliminate the need to install two separate devices. Have an available neutral wire terminal that allows them to be installed in either two-wire or neutral wire installations. Connecting the neutral wire to a Hybrid Keypad allows a lower minimum load to be used. Also, normal keypad operation will be available even if the attached load is not installed or if the lamp is burned out.
