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.
