Miniature Pushbuttons
Series KB
Distinctive Characteristics
Square, rectangular, and round shaped caps.
Latchdown feature gives indication of circuit status. Audible
and tactile feedback with smooth and responsive operation.
Snap-action mechanism for long life.
Stainless steel frame on snap-in models has a specially
designed projection, which prevents rotation and
correctly orients switch in panel.
12mm body diameter.
Molded-in terminals lock out flux, dust, and other
contaminants.
8mm panel thickness capability. Rear panel bushing
or snap-in mounting.
Optional PCB adaptors in straight and right angle types.
Matching illuminated switches available and shown in the
Illuminated section.
Matching indicators available and shown at the end of Section M.

ASSEMBLY INSTRUCTIONS
Cap Removal & Installation
Cap Replacement
For alternate action models cap must be in UP position for cap
removal. Indentations on opposite sides of the cap provide an
easy way to lift the cap out of the holder, using either the finger
nails, or cap extractor AT109.
AT109 Cap Extractor
Note that the cap has a pair
of round tabs and a pair of
long tabs which should be
used for correctly replacing
the cap in its holder. Using
the long tabs as guides,
slide the cap with the long
tabs moving into the slots
on opposite sides of the cap
holder. Then, the round tabs
will snap into notches on the
other two sides of the holder.
