   SERIES 401 DISPLAY SCREENS

Display screens with contoured face give a better operation "feel". Rectangular shape provides greater area for engraving legends and symbols. Entire screen is illuminated by single or twin lamp indication. Various brightness and color combinations are possible by use of legend filter and split face inserts.

SERIES 404 LEGEND INSERTS

Small translucent inserts provide special color effects. White colored insert (40405) has a special matte surface for in-the-field identification with ink, pencil or lettering transfers. Special color effects can be accomplished with combination of a colored insert with a clear display screen. IMPORTANT: Order legend insert (40412) with every pushbutton.

SERIES 407 SPLIT-FACE INSERTS

Split-face inserts provide separate control or indicating functions through the use of color. Ideal for use on Series 38000 Littel Multi-Switch switches where each pushbutton can serve as two indicator lights. Up to two lamps can be used per display screen which are split lengthwise by 2-color split-face inserts. Inserts may be hot-stamped. Order (406) light divider when "flip-flop" lighting is specified; or for redundant lighting where a definite visual indication of lamp failure is desired. A frequently used combination is red and green. Red might indicate danger, stop, etc. Green, go, "okay", etc. IMPORTANT: Use (40212) clear insert with a split-face insert.

SERIES 402 FILTER INSERTS

Inserts add greater color definition. Ideal for use under low ambient lighting conditions where brightness of illuminated pushbuttons must be minimized. A white filter insert (40205) is useful in cutting down the brightness of a white color insert and a white or clear display screen. However, it is omitted when color display screen is used. Filters also diffuse light evenly over entire face of display screen with no "hot spots" or darkened corners. IMPORTANT: Order clear insert (40212) for use with every color filter insert. Clear insert snaps in button housing behind a color filter insert and serves as a heat shield.



406 LIGHT DIVIDER

A light divider is used in the standard pushbutton housing to separate the illumination from the twin lamps used in the Series 38000 Littel Multi-Switch switches. Order a light divider for every pushbutton station in the Series 38000 where split-face lighting has been specified.

Series 405 PUSHBUTTON HOUSINGS

One-piece housing for all 37000 and 38000 switches. Accepts Series 401, 402, 404, 406 and 407 components. Standard color is black. Other colors available.
