B3W-9 Series Tactile Switches

The 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.
