NKK Switches' GB2 Series pushbutton switches feature a miniature footprint
NKK Switches unveils its GB2 Series of ultra-thin and ultra-miniature pushbutton switches. The GB2 series addresses the demands of design engineers for low-cost, reliable and effective solutions for even the most intricate of designs. With a footprint of just 7 millimeters high, 7 millimeters wide and 2.5 millimeters thick, the GB2 pushbuttons are designed for high-density PCB mounting and other applications where board space is at a minimum. These switches are also suitable for block or ganged mounting.
The GB2 Series features off-center plungers that further facilitate mounting in tight spaces, and the plunger design also helps prevent accidental actuation. In addition, NKK’s Sliding Twin Crossbar contact mechanism provides logic level switching reliability and a positive, smooth detent actuation. These switches are momentary circuit, single pole-single throw and feature an OFF momentary ON configuration. They carry a rating of 0.4VA maximum at 28V AC/DC maximum and their mechanical and electrical life is recommended for 50,000 operations minimum.
The GB2 Series switches are constructed of glass fiber reinforced polyamide and have a flammability rating of UL94V-0. They can be ordered in straight PC, straight PC with support bracket and right angle bracketed PC in a single or double switch mounted configuration. The PC footprint is a standard 2.54 millimeters by 2.54 millimeters for easy PCB layout and terminals are molded-in and epoxy sealed to lock out flux and other contaminants.
Red, black or white pushbutton caps can be specified, and a mounting bracket for block mounting is also available.
