The Series 76-97 is robust. The switch body and
button are made from hard-wearing plastic and
produced in front mounting style. The 76-97
series is available as momentary or maintained
action. In addition the buttons have a brightly
colored switch indicator which gives an “at a
glance” recognition of the mode currently in use.
Buttons and status rings can be supplied in a
variety of colors. The 76-97 utilizes ITW Switches’
proven Series 16 snap action switch.

OUNTING AND
C
ONSTRUCTION
:
The 76-97 mounts easily into panels not exceeding .235” (6mm) thickness. Front
panel sealing to IP67 is achieved by use of the sealing washer which is fitted to
the switch before it is inserted into the panel hole cut out. It is held into the panel
by means of a lock nut, tightened down to a torque of between 13 lb/in (1.5 Nm)
to 25 lb/in (2.85 Nm) to achieve the correct sealing pressure. It is mounted into a
standard .885” (22.5 mm) diameter and a double “D” flat is provided to prevent
rotation if required (.800 between flats). Thread size —M2 x 1.5 ISO metric thread
to British Standard 3643.

NFORMATION
:
The Series 76-97 has a non-standard option of 2 poles. The 2 pole switch is
provided separate to the switch body and must be fitted, via a spring clip,
after the switch body has been mounted in the panel.
