Mounting directions for the LED/lamp and
Screen
The
OMRON screen doubles the roles in which a pushbutton switch
is
normally used. The screen may be inserted one of two ways:
1. For
operation as a lighted pushbutton switch, fit the LED/lamp
so that its guide projection is inserted into the
wider opening in
the
receptacle of the screen.

2.
For operation as an indicator unit, insert the LED/lamp guide
projection into the narrower opening in the indicator unit’s
receptacle.
Push the projection of the LED/lamp in the groove
of
the screen so that the LED/lamp is firmly inserted into
the
screen of the indicator unit.

Note:
The inserting direction of the LED/lamp for the screen is
opposite to that for the indicator unit. Pay attention to the
mounting
direction of the legend plate.
Removing the pushbutton unit
While
holding the recessed portions on both sides, firmly and steadily
pull
out the top of the screen with your thumb and forefinger
. Pulling
out the cap with pliers or a similar tool will damage the cap.

Mounting the switch unit on panel
Nut mounting
Insert
the switch unit from the front of the panel and tighten the
mounting
nut inserted from the rear of the panel.
Since
a projection exists on the rear portion of the switch unit, if the
mounting
unit cannot be fitted into position, turn the nut slightly
.
The
tightening
torque of the mounting nut should be less than
5kg–cm.
Solder the terminals after mounting the nut. Otherwise, the
terminals, when thickened by solder, may prevent the nut from
being
screwed down onto the switch unit.
Wiring
Finish soldering within 5 seconds with a 30 watt soldering
iron,
or within 3 seconds at a solder temperature of
240
C.
Do not apply any force to the switch unit for about a minute
after
soldering, to avoid deforming the softened plastic base
of
the switch unit.
Use a non-corrosive, resin-based soldering flux.
