Housings with a full bezel can be front
panel or sub-panel mounted, individually
or in strips.
Barrier type housings are normally
mounted top-of-panel in strips, but can
also be individually mounted. Barriers
can be on either the short or long housing
sides.
The drawing shows how housings with a
barrier on one side are used in a strip of
two or more units. The first has a barrier
on two sides, while all other units have a
barrier on one side, and butt against each
other.
1. Lamps and legends can be changed
from panel front. When button is re-
moved, lamp is extracted from its
socket and retained in button.
Gold alloy contacts —
0.1 amp, res., 30 VDC;
1 amp, 125 VAC.
LOCKED BUTTON OPTION
Series 4 can be furnished with a locked
button option for use in areas accessible
to the public, where tampering and van-
dalism are problems. The housing has a
special mounting clip with built-in button
retainer. This mounting clip must be re-
moved from behind panel to allow button
removal. Button movement during switch
operation is unaffected by locked button
feature. (These units cannot be relamped
from front of panel.)
Barriers on
both sides.
Barriers on
one side.
2. Ease of lamp replacement. After the
inoperative lamp is automatically re-
moved with the button, the new lamp is
inserted without the use of tools.

MOUNTING CLIP ORIENTATION
Mounting clips on the
long sides
of the
housing are specified when individually
mounted or when the long sides of strip
mounting housings parallel the long
sides of the panel cutout slot. The most
secure mounting is achieved when the
mounting clips are on the long sides.
Mounting clips on the
short sides
of the
housing are specified when short sides of
strip mounted housings parallel the long
sides of the panel cutout slot.

LEGENDING
Pad printed legends
Use Legend Order Sheet FO-63039 (see
page 110) to specify pad printed legends.
Reproduce it on your office copier. Leg-
ends are oversprayed for maximum dura-
bility.
Film legends
Film legends are not supplied by MICRO
SWITCH. However, this service is readily
available from commercial sources or
may be provided through your in-house
capabilities. The film should be polyester
to withstand lamp heat and must be preci-
sion cut, per the dimensions shown on
the next page, to insure proper alignment.
The film fits into a small undercut on the
face of the button insert. The film is held
securely when the outer button and insert
are snapped together. (Note: It is difficult
to disassemble for legend changes with-
out damaging the parts.)
Button and insert should be snapped to-
gether prior to being assembled to the
button shell.
Button
Button and metal shell
Example:
4B1AGN
Green (transmitted color) unlegended
button. (If the button shell is also desired,
substitute 4B2 for 4B1.)
Note: legended button should be assem-
bled as shown above, with button notch
keyed to lamp removal slot in shell. This
will reduce possibility of lamp droppage
when button is removed from the hous-
ing. Buttons are legended in this manner.
