The BB series of pushbutton switches incorporate NKK’s award winning sliding twin crossbar contact mechanism. This contact design ensures unparalleled switching reliability and smoother positive detent action. These pushbuttons were specifically designed for logic level applications. This series is unique in that it features an antistatic superstructure, consisting of a carbon impregnated bushing. When configured with a support bracket, it prevents static discharge to the contacts. Static electricity from the operator’s touch travels from the actuator through the bushing and bracket to the PC board.

The BB series of pushbuttons are available in both single and double pole and momentary and maintained actions. The maintained action versions are the smallest in the world and have a latch down feature that provides visible, audible and tactile feedback.

The body of the BB series, including the bushing, is a compact 0.515” in height. The single pole version is .268” wide and the double pole is .346”. These measurements include a bushing .106” long. The terminals are .100” X .100” spacing and conform to standard PC board grids for easier board layout. Engineers can specify from several different mounting options, which include straight PC in bracketed and unbracketed models, vertical and right angle mounts.

NKK’s BB series are process sealed and feature a totally sealed body construction that prevents contact contamination and allows time and money saving soldering and washing. Ultrasonically welded terminals lock out flux and other contaminants. The case housing is constructed of glass-reinforced polyamide.

The BB series pushbutton switches are rated 0.4VA maximum @ 28V AC/DC maximum. The mechanical and electrical life ratings are 50,000 operations minimum for momentary circuits, and 25,000 operations minimum for maintained circuits.
