NKK Switches has introduced the GB series of ultra-subminiature pushbutton switches with fully illuminated plungers. The fully illuminated clear polyamide plunger is designed to produce high-visibility status indication and is available with red, green or amber LED illumination. The ultra-miniature size of the pushbutton switches allows for high-density mounting and their lightweight makes them suitable for handheld devices.

Featuring a completely sealed body construction to prevent contact contamination, the GB series switches also allow for automated soldering and cleaning. The insert-molded terminals lock out flux, solvents and other contaminants, guaranteeing a long mechanical and electrical life of 50,000 operations minimum. NKK's STC contact mechanism has also been incorporated into these switches, which provides a smooth and positive detent mechanism, increased contact stability and high logic-level reliability.

Terminal spacing is 2.54mm x 2.54mm, which conforms to standard PCB grid spacing, and their round terminals facilitate through-hole mounting. The series is available in an SPDT momentary circuit configuration with straight, right angle or vertical PC mounting terminals. The current rating is 0.4VA maximum at 28Vac/dc maximum.

Pricing starts at $2.91 each in quantities of +2,500.
