| Process Sealed Subminiature Antistatic Pushbuttons Series BB Distinctive Characteristics Subminiature size (1/3 size of Series M switches) saves space on PC boards. Specifically developed for logic-level applications. Available in momentary and maintained circuits. Industry's smallest alternate action (maintained) pushbutton with latchdown feature providing visible, audible, and tactile feedback. Antistatic superstructure, consisting of the carbon impregnated bushing and the support bracket, prevents static discharge to the contacts. Static electricity from an operator's touch travels from the actuator through the bushing and bracket to the PC board. Award-winning STC contact mechanism with benefits unavailable in conventional mechanisms: smoother, positive detent actuation, increased contact stability and unparalleled logic-level reliability. (Additional STC details in Terms & Acronyms; see Supplement section.) Smooth, 6mm diameter bushing simplifies panel layout. Totally sealed body construction prevents contact contamination and allows time- and money-saving soldering and cleaning. .100" x .100" (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grids.

Standards & Certifications Flammability Standards: UL Recognition or CSA Certification: UL94V-0 available The BB Series pushbuttons have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy. 03-07 NKK Switches * email: sales@nkkswitches.com * Phone (480) 991-0942 * Fax (480) 998-1435 * www.nkkswitches.com Process Sealed Subminiature Antistatic Pushbuttons TYPICAL SWITCH ORDERING EXAMPLE Series BB A BB POLES 1 2 SPDT DPDT 1 5 A H F PC TERMINALS P *B *H *V W Straight Straight with Bracket Right Angle with Bracket Vertical with Bracket Straight Long CIRCUITS 5 6 ON ON (ON) ON ( ) = Momentary Alternate Action has Latchdown.
