Note: 1. Pushbutton units, lamps (lighted type only), case, and socket must be ordered separately.
Example: Pushbutton unit A3BJ-500R, Case A3GJ-6011-1, Socket A3G-4011.
2. Illumination: red, yellow, and white use either LED or incandescent lamps.
3. With the exception of green, all pushbutton units can be used with either LED or incandescent lamps. To avoid an
undesirable hue change with green pushbutton units, use a green LED lamp with a green LED pushbutton and an
incandescent lamp with a green incandescent pushbutton.
