Subminiature Tactile Switches Illuminate Red, Green, Or Yellow

Designed for both aesthetics and cost reduction, the JB series of illuminated subminiature tactile switches provide full face LED illumination in red, green, or yellow. An array of cap styles and colors including flat translucent, flat with lens and diffusers, or button framed are available. In addition, designers can choose from two actuator heights, and between standard or high operating force in relation to the series’ sturdy dome contacts. The high operating force models offer more pronounced feedback to help ensure positive circuit transfer. Custom keyboards can be designed with switches and caps already installed and fit through panel cutouts. Unique legends are then added via laser etching. The switches are 10 mm², with straight PC. Terminals are slanted to provide a spring type action, ensuring secure PCB mounting that prevents dislodging during wave soldering. Terminal spacing conforms to a standard .100-in. (2.54-mm) PCB grid. The JB Series also features a rubber seal construction that prevents contact contamination and allows automated soldering and cleaning. The process sealed construction helps provide a long mechanical and electrical life of 5 million operations minimum. JB Series switches are single pole single throw (SPST) with a momentary circuit and rated at 50 mA@24 VDC maximum for standard operating force models, and 125 mA@24 VDC maximum for high operating force models. Operating temperature range is -25°C to +70°C. NKK SWITCHES, Scottsdale, AZ. (480) 991-0942.
