Subminiature Pushbuttons
Series HB
Distinctive Characteristics
Compact front panel design with 9mm square or round bezel.
Rear panel threaded mounting. Behind panel depth of less than
one inch. 8mm body diameter fits common size panel cutout.
Latchdown feature gives indication of circuit status.
Audible and tactile feedback with smooth and
responsive operation.
Dual, sliding contacts with self-cleaning action
provide contact stability, high reliability, and
increased operating life.
Solder lug terminals have spacing of .100” (2.54mm)
for choice of mounting.
Longer normally closed terminal facilitates wiring
and soldering.
Molded-in terminals lock out flux, dust, and other
contaminants.
Illuminated models available and shown in the
Illuminated Pushbutton section.
Matching indicators available and shown at the
end of Section M.

Solder lug terminals are spaced .100” x .200” (2.54mm x 5.08mm).
This enables PCB mounting which can be accomplished by elongating
PC board holes to .080” (2.03mm).
