NKK Switches | IS-L0271-C

The LCD 36x24 logic boards are PCB’s that have mount positions for one or more LCD 36x24 SmartSwitches or SmartDiplays. The switches/displays can be mounted directly on the logic board or on a socket mounted on the board. One or two switch boards are the most common but logic boards with other configurations are available as well as custom designs.

They have some “glue logic” for converting the backlight addressing and switch scanning to serial, and therefore many logic boards can be daisy-chained via 14-pin ribbon cables. The switch numbering is according to their order in the daisy-chain, where the switch number one is on the logic board connected directly to the controller. Many controllers are designed to work either with 4-bit or 2-bit logic boards.

There are four types of LCD 36x24 logic boards;

• Bicolor/Monocolor pushbutton
• RGB pushbutton
• Bicolor/Monocolor/RGB display
• Bicolor/Monocolor/RGB compact

Features :
