B3W-9 Series Tactile Switches

Compact LED Illuminated Tactile Switch

image of Omron's B3W-9 Series illuminated tactile switchThe Omron B3W-9 series of SPST-NO (momentary) configuration LED illuminated tactile switches are available in red, yellow, blue and green LEDs. The keycaps utilize a proprietary diffusion panel to deliver uniform brightness across the entire surface. The B3W-9 is available in one, two or three color light models. The “tri-color” is accomplished when the red and green LEDs are simultaneously illuminated beneath the white keycap producing the third color, orange.

The switch utilizes Omron’s proven B3W switching mechanism creating a space saving 10 mm x 10 mm or 12 mm x 12 mm key cap area with a low profile of 11 mm height. They have the same footprint as the B3W with the exception of the added LED connections on the PCB.

The B3W-9000 has an operating force of 160 gf typical with a minimum service life of 1,000,000 operations. The contacts have a restive load rating of 5 through 24 VDC at 1 to 50mA while operating in a temperature range of –25°C to +70°C in 35% to 85% humidity without icing or condensation.

This series of switches is fully RoHS compliant and features a dust tight switching mechanism. These switches are ideal for use in applications requiring visual feedback confirming operation including test and measurement, office automation, amusement, industrial controls, and medical devices.

  • Compact construction (10 x 10 x 11 mm and 12 x 12 x 11 mm heights available) with bright and uniform illumination
  • Monocolor illumination, with 1 or 2 LEDs
  • Three-color illumination possible (red LED + green LED = orange)
  • Keycap option includes LED color match, transparent or opaque white
  • Dust tight internal switch mechanism
  • RoHS Compliant
