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
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.
or CSA Certification:
