Omron Intros Innovative Tri-Color Tactile Switch
Momentary tactile LED switches.
Schaumburg, IL — Omron Electronic Components LLC has introduced the B3W-9 series of SPST-NO (momentary) configuration LED illuminated tactile switches. The switches are available in red, yellow, blue, green and bright green LEDs. The keycaps utilize a proprietary diffusion panel to deliver uniform brightness across the entire surface and are available in color matched transparent or translucent white versions.

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 the company's proven B3W switching mechanism creating a space-saving 10 x 10mm key cap area with a low profile of 11mm in height.

The switches have the same footprint as the B3W with the exception of the added LED connections on the PC board. The B3W-9000 has an operating force of 160gf typical with a service life of 1,000,000 operations minimum while the B3W-9002 has an operating force of 230gf typical with a service life of 300,000 operations minimum. The contacts have a restive load rating of 5 through 24VDC at 1 to 50mA while operating in a temperature range of -25 to +70°C in 35 to 85 percent humidity without icing or condensation.

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