Pushbuttons
The 16mm dia. series of compact size
pushbuttons are 'finger-size', and
consequently take up little panel space.
AH165-2 series operators are about twice
as large as the AH164 and AH165 series
operators for easier operation. With many
types of operator available, the most
suitable switch can be identified by color,
shape and legend, and have a smooth,
quality "snap-action". In spite of their small
size they have a highly reliable

mechanism, and are eminently suited for

series contact block holders can easily be
removed manually. Moreover, the contact
block can be easily attached or detached
without using any special tools, thus
facilitating addition or replacement of
contact.
Easy color change
Safety
Color lenses fit over the inner button.
The lens can easily be removed using a
small screwdriver
FUJI’s original Trigger Action mechanism
is used in the emergency stop
pushbuttons. They are suitable for
emergency stop and safety. This
mechanism prevents the contacts from
moving until the button is pushed and
locked.

Selector switches
Screw driver
Selector switches can also be supplied
in either knob-handle operated or key
operated types.
Note: The luminous color of LEDs and neon illumination
types varies with the body color of the product.
Visible inscription
Button legends are printed on legend
sheet, which is stuck to the legend plate
on the inner button.
The lettering is back lit by the switch
lamp and the inscription is highly visible
through the color lens.
Strong construction
Alternate action
The operator and contact blocks are
molded from an excellent thermal
resistance resin and can withstand the
heat at the time of soldering.
In the case of alternate action when
the button is depressed the contacts are
maintained and remain so even if the
finger is removed. The button will not
return to its free position. In order to
remove the lock, the button must
be given a second pressure before the
button will return to its free position. This
makes it most suitable as the switch for a
power source.
Since these pushbuttons are

such causes as loose bases.

Excellent switch reliability
The switch uses a snap-action
mechanism. The pushbuttons are
available with either momentary or
alternative actions. The snap-action
switch has a double break movement
which operates independently of the
speed of switching. The contacts are
made from gold-flashed silver. High
contact reliability of 1mA at 5V AC/DC is
assured. Contact blocks are available in
1NO+1NC to 3NO+3NC arrangement.
Maintain
Quality feel tough
Both the operator and contact block are
precisely engineered. There is no fear
of the switch malfunction even after
long use and it continues to operate
smoothly for its service life of about
1,000,000 operations.
Pushbutton with finger guards
Finger guards are provided for square or
rectangular type pushbuttons (SF, TF, SL
and TL types) in order to prevent
