Series BB Process Sealed Subminiature Antistatic Pushbuttons s e gl Distinctive Characteristics g o T s er k c Subminiature size (1/3 size of Series M switches) saves space on PC boards. o R s n Specifically developed for logic-level applications. C utto b h s u P Available in momentary and maintained circuits.
