The 1X6 Molded Elastomer Technology six-position keypad has single-pole, single-throw momentary action switches. Each actuation button features customer-defined, laser-etched legends on a plastic keycap. The charcoal-black units can be lighted or unlighted. Their ability to resist dust, water, and humidity suits them for manufacturing and industrial environments. A single unlighted keypad costs about $50.
